use of appropriate accessories.Install the unit vertically:●Avoid placing it close to heating elements●Leave sufficient free space to ensure that the air required for cooling purposes can circulate from the bottom to the top of the unit. ClearanceMounting TypesType A MountingType B MountingType C MountingBy removing the protective blanking cover from the top of the drive, the degree of protection for the drive becomes IP 20.The protective blanking cover may vary according to the drive model (refer to the user guide).Specific Recommendations for Mounting the Drive in an EnclosureVentilationTo ensure proper air circulation in the drive:●Fit ventilation grilles.●Ensure that there is sufficient ventilation. If there is not, install a forced ventilation unit with a filter. The openings and/or fans must providea flow rate at least equal to that of the drive fans (refer to the product characteristics).●Use special filters with IP 54 protection.●Remove the blanking cover from the top of the drive.Dust and Damp Proof Metal Enclosure (IP 54)The drive must be mounted in a dust and damp proof enclosure in certain environmental conditions: dust, corrosive gases, high humidity with risk of condensation and dripping water, splashing liquid, etc.This enables the drive to be used in an enclosure where the maximum internal temperature reaches 50°C.Product data sheetATV61HD22N4ZConnections and SchemaWiring Diagram Conforming to Standards EN 954-1 Category 1, IEC/EN 61508 Capacity SIL1, in Stopping Category 0 According to IEC/EN 60204-1Three-Phase Power Supply with Upstream Breaking via ContactorA1ATV61 driveKM1ContactorL1DC chokeQ1Circuit-breakerQ2GV2 L rated at twice the nominal primary current of T1Q3GB2CB05XB4 B or XB5 A pushbuttonsS1,S2T1100 VA transformer 220 V secondary(1)Line choke (three-phase); mandatory for ATV61HC11Y…HC80Y drives (except when a special transformer is used (12-pulse)).(2)For ATV61HC50N4, ATV61HC63N4 and ATV61HC50Y…HC80Y drives, refer to the power terminal connections diagram.(3)Fault relay contacts.

The parallel Linear LED driver channel structure associated with the power conversion stage covers mainstream applications for many LED Lighting dimming and color tuning applications. Given the maximum operating input voltage at 60V, it is possible to drive more than 16 RGB emitters by splitting LED Emitter string voltage and VIN, as long as it is below 60V.The AL1783 is a three PWM current sink regulator. In order to meet channel current accuracy and short protection requirements, the recommended maximum current of each channel is 250mA and the recommended minimum channel current is 30mA. Each channel can be individually and digitally controlled by the PWM dimming the signal down to less than 1%@1kHz.As in the case of three-channel Tunable Color LED lighting, the AL1783 drives three emitter strings. Using R REF1, R REF2, and R REF3of 24KΩ, the maximum output current for Channel 1, Channel 2, and Channel 3 will be 250mA when each PWM signal is turned on. The associated micro-controller unit (MCU) shall program and generate the suitable PWM duty cycle to meet the required and targeted Tuning Color output. R REF1,R REF2, and R REF3 can also be set dynamically for different peak values to achieve the desired channel peak current if another dimension adjustment is needed.The LED Driving Element detects fault conditions and reports its status on the FAULTB pin. It features LED open detection, LED short detection, Over Temperature Protection (OTP), and Under Voltage Lockout (UVLO). The AL1783 provides supreme current matching between channels and devices. Along with bus-mode fault reporting, multiple devices can be employed together to increase current driving capabilities or channel count versatility.Interface with Emitter StringsThe Power Conversion stage provides necessary constant output voltages (CVs) to power the micro-controller unit (MCU), LED Strings, and LED Drivers. A typical application requires 3.3V for the MCU and 12V/24V/48V anodes of LED emitter strings. The cathodes of the bottom LED emitter strings are connected to the LED1,2,3 pins of the AL1783.Interface with MCUThe physical layer interfaces between the micro-controller unit (MCU) and the AL1783 are the PWM1,2,3 pins and FAULTB. The MCU activates the PWM1,2,3 (asserted high) to turn on AL1783 during normal LED lighting operation applications. When the PWM1,2,3 pins are asserted low and greater than > 4ms, the device enters into Standby Mode with minimum power consumption. For typical light dimming or mixing operations, the MCU generates proper dimming control output signals to the PWM1,2,3 pins. If any general fault occurs in the AL1783, the FAULTB pin is asserted LOW to interrupt and request the MCU to take proper actions.Application Information (cont.)Current SettingThe AL1783 is designed to have individual LED channel currents set by its corresponding current setting from the R SET1,2,3resistor. The LED channel current level is expressed as below:ILED1,2,3=4000∗VREFRSET1,2,3wℎere VREF=1.5V nominally for all cℎannelsFor example, when an R REF of 24KΩ is used, each channel of the AL1783 provides the same output current of 250mA.The maximum LED current for each channel can be adjusted up to 250mA via the R REF resistor for AL1783. Any two or more channels can be tied together to drive one LED string with aggregated current. So when the current needed for any channel is greater than the maximum value the device can provide, two or more channels or devices can be connected and paralleled together to provide the higher drive current necessary. Support Higher CurrentWhile the recommended maximum operating current is at 250mA for each channel, and total 750mA for the AL1783, by setting R REF1, R REF2, and R REF3 at 24KΩ; the system design can drive an LED string with higher current by connecting the cathodes of the LED emitter string to two or more LED channel outputs (LED1,2,3) and tie the associated PWM pins (PWM1,2,3) to the same PWM signal from the MCU. The total current through the LED emitter string is the sum of the current through each individual channel.Similarly, it is also possible to further increase the current for a specific LED string by connecting two or more AL1783 IC chips in parallel and drive all associated PWM pins with a common PWM signal.PWM Dimming ControlA PWM frequency greater than 500HZ is recommended. A high level of PWM signals will turn the current sink on to flow through the LED pin, and a low level will turn it off. Consequently, each LED channel and LED brightness of the corresponding channel can be adjusted cycle-by-cycle accordingly.The pulse width of the PWM signal should be no less than 10μs, supporting down to 1% @ 1 kHz deep dimming capability. PWM signals can be driven static high/low to turn on/off the corresponding channels.Enable and Soft-Start LED Drivers (EN Pin)The PWM of the AL1783 is enabled when the voltage at any PWM1,2,3 pin is greater than the typical voltage of 2.5V, and disabled when all PWM1,2,3 are lower than 0.4V. When PWM1,2,3 pin is asserted and the VIN pin is ramped up beyond minimum operation voltage, a soft start will be performed with a slew-rate controlled current ramp over 200μS at the LED1,2,3 output pins. For optimal system reliability, this minimizes the current overshooting through the LED strings. When all PWM1,2,3 are asserted low for > 4ms, the LED Driver will enter into Standby Mode with ultra-low standby power < 200μA.Standby ModeWhen in this Standby Mode, the power consumption saved is I vin_standby (Standby Power Supply Current) * VIN (VIN for LED driver circuit). Refer to the case of the R REF at 24KΩ (fo r 250mA channel current in the AL1783, I standby is typical at 0.2mA) and VIN is 50V, or 10mW for the LED driver portion.When any PWM signal driving AL1783 is detected, the AL1783 will automatically exit the standby mode and perform the designated functions properly.Application Information (cont.)Fault Reporting (FAULTB Pin)The AL1783 detects and reports the FAULTB status upon the occurrence of Thermal Shutdown in OTP, LED Short, LED Open, and UVLO. The FAULTB pin is an open-drain output design. Multiple devices can share a single FAULTB signal by connecting all FAULTB pins together with an external pull-up resistor.Under Voltage Lockout (Hysteresis Mode)Under-voltage lockout function (UVLO) guarantees that the device is initially off during start-up. The AL1783 is not turned ON until the power supply has reached 6V. Whenever the input voltage falls below approximately 5.7V, the device is turned off and the FAULTB status will be reported. The UVLO detection-trigger circuitry has a hysteresis of 300mV.LED Open Protection (Hiccup Mode)The AL1783 detects the LED status by monitoring the current of the LED pin. When LED opens and lasts for a period of time period, the AL1783 enters protection mode and shuts down all channels. The time period is 7 cycles of the input PWM signal or 3ms timer when the PWM duty is 100%. The abnormal channel will be retested afterward to check if the abnormal condition is cleared. The AL1783 periodically checks every 128ms if the abnormal condition is removed. The LED driver will re-activate once the abnormal condition is cleared. The LED open protection is effective when the input PWM1,2,3 signal on time is higher than 10μs, or 1% @ 1 kHz. The FAULTB pin will be asserted low when the LED pin detects that the LED string is open, and will resume high once the LED open condition is removed.LED Short Protection (Hiccup Mode)The AL1783 detects the LED status by monitoring voltage at the LED1,2,3 pins. When the LED string anode is short to cathode, V LED1,2,3 will be pulled up. When V LED1,2,3 voltage exceeds 15V and lasts for a short time period, the AL1783 enters protection mode and shuts down all channels. The time period is 7 cycles of the input PWM signal or 3ms timer when the PWM duty is 100%. The abnormal channel will be periodicallyrechecked every 128ms afterward to detect if the abnormal condition is cleared. The LED driver will re-activate once the abnormal condition iscleared. The LED short protection is effective when the input voltage is higher than 15V and the input PWM1,2,3 signal on time is higher than 10μs, or 1% @ 1 kHz. The FAULTB pin will be asserted low when the LED shorts, and will resume high once the LED short condition is removed.Thermal Foldback and Over Temperature Protection (Hysteresis Mode)Temperature is a concern when driving the LEDs at high currents. Take care at high temperatures so as to not exceed the LED operating temperature requirements. In order to cool down the LEDs before they are damaged, the current going through the LEDs must be decreased when the LED temperature begins to increase.When the chip temperature is higher than the threshold temperature (130°C), the AL1783 starts to reduce the V REFX voltage and the LED current starts to fall from the nominal current. As illustrated in Figure 3, the LED current decreases as the temperature increases.L E D C u r r e n t P e r c e n t a g e (%)Temperature (ºC)Figure 3. Thermal Fold-back DiagramThermal protection prevents the IC from being damaged when the temperature exceeds safe margins. When the junction temperature reaches 160ºC, the device will enter thermal shut down, and all currents will sink and while no current flows to the LED strings. The normal current level can be automatically restored to its set current from OTP by triggering a Soft Start once the temperature cools down below 140ºC. The LED Driver’s Thermal Shut Mode will also be reported at the FAULTB pin.Ordering InformationAL1783 T16E - XPackageT16E: TSSOP-16EP13: Tape & ReelProduct NamePackingPart Number Package CodePackaging 13” Tape and ReelQuantityPart Number SuffixAL1783T16E-13T16ETSSOP-16EP (Type DX)(Note 8)2500/Tape & Reel-13Note:8.

MIC2297 600kHz 42V OVP PWM白色LED驱动器说明书
MIC2297 Evaluation Board600kHz 42V OVP PWM White LED DriverMLF and Micro LeadFrame are registered trademarks of Amkor Technology, Inc.Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 (408) 944-0800 • fax + 1 (408) 474-1000 • General DescriptionThe MIC2297 is a 600kHz PWM White LED Driver optimized for 6 to 10 series WLEDs. With an output voltage of up to 42V and a guaranteed 1.2A on the internal power switch, the MIC2297 can easily drive 10 WLEDs at 20mA continuous current. The MIC2297 features WLED brightness control using the BRT pin and has output over voltage protection (OVP) to protect the device in case the WLEDs are disconnected unexpectedly. Available in a tiny 10-pin 2.5mm x 2.5mm x 0.85mm MLF ®package, the MIC2297 solution only requires a total of 6 external components. The MIC2297 operates at a default (BRT pin is open)feedback voltage of only 200mV. The low feedbackvoltage reduces the power dissipation from the externalcurrent set resistor and increases total operatingefficiency.When brightness control is required, the MIC2297 features brightness control by applying a DC voltage to the BRT pin. When applying a DC voltage to the BRT pin, the feedback voltage is equal to the BRT voltage divided by 5. This feature essentially increases or decreases the feedback voltage from its default value (200mV), changing the WLED current to control the WLED brightness. Alternatively, a PWM signal may also be applied to theBRT pin for brightness control. When a PWM signal (1kHzrecommended) is applied to the BRT pin, the WLEDs aredimmed depending on the duty cycle and the peak voltageof the signal. The PWM frequency can range from 1kHz to1MHz. The selected PWM frequency does not affect theWLED brightness. Assuming a 1V PWM signal is applied,as the duty cycle decreases, the feedback voltagedecreases, thus reducing the WLED current.RequirementsThe MIC2297 evaluation board requires an input power source that is capable of delivering greater than 1.2A at 2.5V.PrecautionsThe evaluation board does not have reverse polarity protection. Applying a negative voltage to the V IN terminal may damage the device.The MIC2297 evaluation board is tailored for a single or dual Li-Ion input source. The input voltage should never exceed 10V.Getting Started 1. Connect an external supply to V IN . Apply desired input voltage to the V IN (J1) and ground (J4) terminals of the evaluation board, paying careful attention to polarity and supply voltage (2.5V ≤ V IN ≤ 10V). An ammeter may be placed between the input supply and the V IN (J1) terminal to the evaluation board to accurately monitor the input current. The ammeter and/or power leadresistance can reduce the voltage supplied to the input; therefore, the supply voltage at the V IN (J1) terminal should be monitored. 2. Enable/Disable the MIC2297. To enable the MIC2297, apply a 1.5V or greater voltage signal tothe EN (J2) terminal. To disable the device, pull the EN (J2) pin below 0.4V. The evaluation board is configured with a jumper (JP1) from V IN to the enable pin and a 10k pull-down resistor to ground to conveniently turn the part on or off. Connecting the jumper (JP1) will enable the MIC2297, while removing the jumper will disable the part. 3. DCV Brightness Control. To control the brightness with a DC voltage, see the DVC Brightness Control section. 4. PWM Brightness Control. To control the brightness with a PWM Signal, see the PWM Brightness Control section. Note: For detailed specifications, please refer to the MIC2297 Datasheet at . Ordering InformationPart Number Description MIC2297-42YML EVEvaluation board with the MIC2297 42V deviceLED Current SettingThere are 10 WLEDs provided with the evaluation board. Two of the WLEDs (D1 and D2) may be by-passed by placing a jumper on JP3. The WLED current (I LED ) is equal to the feedback voltage (V FB = 200mV by default) divided by the R3 resistance value. The evaluation board is provided with R3 equal to 10Ω. The brightness level is proportional to I LED . Programming the feedback voltage changes the I LED , therefore changing the brightness level. I LED = V FB / R3 (1) DCV Brightness ControlThe brightness level can be set by applying a DC voltage (BRT) to the BRT pin. When a DC voltage is applied to the BRT pin, the feedback voltage is changed from the default value of 200mV to: V FB = BRT / 5 (2)Assuming BRT equals 1V, then V FB will be 200mV and ILED may be calculated by: I LED = V FB / R3 I LED = 200mV / 10Ω I LED = 20mASimilarly, if BRT equals 2V, then V FB will be 400mV and the I LED may be calculated by: I LED = V FB / R3 I LED = 400mV / 10Ω I LED = 40mAThe feedback voltage can be changed using the BRT pin. Changing the feedback voltage changes the WLED current, which will change the WLED brightness. Refer tothe Figure 1 and Figure 2 for reference.(D C C o u p l e d )50m V /d i v )F e e d b a c k V o l t a g e TIME (400µs/div)B R T V o l t a g e (DC C o u p l e d )(1V /d i v )Figure 1.

BRT = 2V, V FB = 400mV, I LED = 40mAPWM Brightness ControlThe brightness level can also be set by applying a PWM signal to the BRT pin. To calculate the feedback voltage when a PWM signal is applied to the BRT pin, use the following formula: V FB = V PEAK / 5 * D (3)V PEAK is the peak of the PWM voltage and D is the duty cycle. If V PEAK is 1V and the duty cycle is 1%, then V FB can be calculated by: V FB = 1V / 5 * 0.01 V FB = 2mVThe I LED can then be calculated by: I LED = V FB / R3 I LED = 2mV / 10Ω I LED = 200µASimilarly, if the V PEAK is 1V and the duty cycle is 50%, then V FB can be calculated by: V FB = 1V / 5 * 0.5 V FB = 100mVThe I LED can then be calculated by: I LED = V FB / R3 I LED = 100mV / 10Ω I LED = 10mAWith PWM brightness control, the MIC2297 has great versatility since brightness may be set anywhere from 0 to 100 percent. Refer to the following figures for reference.(D C C o u p l e d )10m V /d iv )F e e d b a c k V o l t a g e TIME (400µs/div)B R T V o l t a g e (DC C o u p l e d )(1V /d i v )Figure 3.

Duty Cycle = 80%, V FB = 160mV, I LED = 16mAIn Figure 7, when the duty cycle is equal to 100%, D equals 1. When we set D equal to 1 in equation (3), notice (3) becomes the same as equation (2), if we assume V PEAK equals BRT. Using a 100% duty cycle is the same as applying a constant DC voltage to the BRT pin. In this instance, Figure 7 is exactly the same as Figure 1.(D C C o u p l e d)50m V /d i v )F e e d b a c k V o l t a g e TIME (400µs/div)B R T V o l t a g e (DC C o u p l e d )(1V /d i v )Figure 7.

If this is detected the faulty channel will be isolated. The RED LED 'wiring fault indicator' will illuminate to confirm this. The iDrive should be turned off at the mains and the fault rectified before powering up the system again.2. The second scan will look for a thermistor on the LED fixture, as recommended in the 'wiring specification' (page 4). If a thermistor is found the 'thermal feedback protection’will be activated in the iDrive.Both these scans take less than 1 second to perform and only take place on initial power up of the system.The iDrive can be used in DMX mode or standalone mode.For DMX SettingsThe rotary switches should be set to between 001and 510. Normally address 0.0.1 is sufficient for a 3channel and master DMX controller.For Stand Alone SettingsThe iDrive contains many pre-set programmes.600 - 636- This setting provides 36 different preset colours - 636 being a white setting, i.e. all LEDS full on.700 - 799- These are the cross fade settings with different speed functions.800 - 819 - Cycle Wash Pre-set.There are two preset cyclic washes, eitherclockwise or anti-clockwise with speed controlMains Indicator - Indicates power onto the iDriveDMX Indicator - When the rotary switches are set to a DMX address i.e. between 001 and 510,this indicator will flash until the iDrive receives a DMX input via the DMX 5-pin XLR input.Once a DMX signal is received, the amber indicator stops flashing and stays permanently on.Wiring Fault Indicator - The iDrive hasshort/open circuit protection.

It applies advanced digital control technology to detect the dimmer type, enabling it to provide dynamic impedance to interface with the dimmer and to control the LED brightness at the same time. With advanced dimmer detection technology, the iW3688 can operate with most wall dimmers including leading- edge dimmers (R-type or R-L type), trailing-edge dimmers (R-C type), and smart dimmers. In addition, the iW3688’s cycle-by-cycle waveform analysis technology allows for fast dimmer transient response.In no-dimmer mode, the iW3688 operates the main power converter that delivers current to the LED load in quasi- resonant mode to provide high power efficiency and low electro-magnetic interference (EMI). When there is no dimmer on the line, the iW3688 optimizes the power factor and minimizes the current harmonic distortion to the AC line. The commonly utilized converter topologies for iW3688 are buck-boost and flyback.The iW3688 uses patented PrimAccurate™ primary-side sensing technology to achieve excellent LED current regulation under different AC line and LED load voltages, without using a secondary-side feedback circuit and thus eliminating the need for an opto-coupler.The iW3688 minimizes the external components count by simplifying the EMI filter with Dialog’s EZ-EMI® technology, and by integrating current sink, switching, and V CC charging circuit. Additionally, the iW3688 does not require an auxiliary winding, which eliminates the need for a custom inductor. The digital control loop of the iW3688 maintains stability over all operating conditions without the need for loop compensation components.The iW3688 maintains high performance wide-range dimming and achieves excellent dimmer compatibility with a simple application circuit.3.0 Applications●Dimmable LED retrofit lamps up to 20W●Dimmable LED luminaires up to 20WSingle-Stage Dimmable LED DriversLFigure 3.1: iW3688 Simplified Application CircuitSingle-Stage Dimmable LED Drivers4.0 Pinout DescriptionFigure 4.1: 14-Lead SOIC-14 PackageSingle-Stage Dimmable LED Drivers5.0 Absolute Maximum RatingsAbsolute maximum ratings are the parameter values or ranges which can cause permanent damage if exceeded.

There are three dimmer modes in the iW3688: no-dimmer, leading-edge dimmer, and trailing-edge dimmer. Based on the detected dimmer type and input voltage waveform, the iW3688 determines whether the iW3688 is operating in current sink mode or switching mode. During switching mode, the output current regulation is determined by inductor peak current (I SENSE pin), the magnetic flux status of the inductor (V D and V CB pins), and the input voltage waveform (V IN pin) (refer to section 9.4 for more information).If no dimmer is detected on the AC line, the iW3688 operates in no-dimmer mode where only the switching circuit is enabled. In this mode, the average output currentis regulated to the nominal value and is immune to input voltage variation.If a dimmer (either leading-edge or trailing-edge) is detected on the AC line, the iW3688 operates in dimmer mode. In dimmer mode, MOSFET (Q1 in Figure 11.1) operates in both switching mode and current sink mode based on the timing control of iW3688. During the switching mode, the output current is adjusted based on the detected phase conduction angle. During current sink mode, the switching circuit is disabled and the current sink circuit is enabled. The main MOSFET is forced to operate in linear mode, where the current through MOSFET is regulated by the Digital Core. As shown in Figure 8.1, V CC can be charged during both current sink mode and switching mode..Figure 8.1 : iW3688 Functional Block DiagramV INV ccV CBI SENSEPGNDCFG1CFG2AGND CFG3CFG4V D V SSingle-Stage Dimmable LED DriversAC line before wall -dimmerAC line after wall -dimmerFigure 9.2 : Leading-Edge Wall Dimmer WaveformsAC line before AC line after wall-dimmerFigure 9.3 : Trailing-Edge Wall Dimmer WaveformsThe dimmer detection stage occurs in the iW3688 immediately after IC starts up. During this stage, the iW3688 stays in current sink mode to place a low impedance load on the AC line, where the current through MOSFET is regulated by the Digital Core. As a result, the dimmer type (no-dimmer, leading-edge, or trailing-edge) can be accurately detected. The dimmer type is determined by sensing the slope of the input AC voltage and the dimming phase angle. A fast rising edge of the input AC voltage indicates a leading-edge dimmer. A large dimming phase angle indicates no dimmer is on the line. Otherwise, a trailing-edge dimmer is detected.When the V IN_A signal is above V IN(ST) for 500µs and the AC line frequency is within the range, the AC input signal is qualified for startup. If V CC drops below V CC(UVL), the iW3688 resets and the startup sequence is initiated.9.1.3 LED Current Soft-StartAfter the iW3688 qualifies the AC input signal, the buck- boost or flyback converter immediately starts to deliver9.0 Theory of Operation9.1 System StartupThis section provides information about iW3688 system start up, which includes the IC startup, wall dimmer detection, and the LED current soft start.9.1.1 IC StartupWhen AC voltage is applied, the gate voltage of MOSFET, V G is charged up through RC circuit (R6, and C5 in Figure 11.1). When V GS > V GS(TH), the MOSFET starts to turn on and charge the V CC capacitors (C7 and C8 in Figure 11.1). When V CC voltage reaches V CC start-up threshold V CC(ST), the iW3688’s control logic is activated and the IC starts up.V CCENABLEStart-up SequenceFigure 9.1 : Start-up Sequence Diagram9.1.2 Wall Dimmer DetectionThere are two basic categories of phase-cut wall dimmers: leading-edge dimmers and trailing-edge dimmers. If the AC voltage rises at the phase-cut edge, the dimmer is called leading-edge dimmer (shown in Figure 9.2). Otherwise it is called trailing-edge dimmer (shown in Figure 9.3). Normally, a leading-edge dimmer is either an R-type or RL-type; a trailing-edge dimmer is an RC-type.Single-Stage Dimmable LED Driverscurrent to the LED load. A soft-start algorithm is applied to the buck-boost or flyback converter to gradually ramp up the LED current.If a dimmer is connected, the driver starts immediately into leading-edge or trailing-edge mode operation (refer to section 9.3.1 and 9.3.2 for details) to interface with the dimmer. If no dimmer is connected, the driver starts no-dimmer mode operation (refer to section 9.3.3 for details). 9.2 Dimming CurveWhen a leading-edge or a trailing-edge dimmer is detected, the iW3688 adjusts the output current to a certain ratio of the nominal output current, based on the dimming phase angle detected. This ratio between the desired output current to the nominal output current is called the dimming percentage.A typical mapping between the dimming phase angle and the dimming percentage is shown in Figure 10.6. All the dimming curves of the iW3688 fall within the limits of the NEMA SSL6 and SSL7 standard (shown in Figure 10.6). The iW3688 updates the dimming percentage every half-AC-cycle based on the detected dimming phase angle to ensure fast dimming response.9.3 Current Sink and Switching CircuitControlThis section provides information about how the iW3688 controls the current sink circuit and the switching circuit during leading-edge dimmer mode, trailing-edge dimmer mode, and no-dimmer mode.9.3.1 Leading-Edge Dimmer ModeIf a leading-edge dimmer is detected, the iW3688 enters into leading-edge dimmer mode. The current sink circuit and switching circuit inside iW3688 turn on alternatively.The current sink circuit and switching circuit control during leading-edge dimmer mode can be split into six operating sections, as shown in Figure 9.4.During section 1, the TRIAC in the leading-edge dimmer is turned off and the dimmer requires a low impedance load to charge its internal timing circuit. The regulated current of the current sink circuit is set to a high limit while the switching circuit is disabled. When V IN_A exceeds 0.228V for more than 40µs, the iW3688 enters into section 2. In section 2, the regulated current of section 1 is gradually transitioned to match the average switching current of section 3. When the transition is over, the iW3688 enters section 3, where the current sink circuit is disabled and the switching circuit begins its operation. The duration of section 3 is determined by the desired output current to be delivered to the LEDs. Once the energy required to obtain the desired output current is delivered to the LEDs, the iW3688 disables the switching circuit and enters section 4. In section 4, the current sink circuit is enabled, which provides a gradual transition of MOSFET source current. During this transition, the averaged MOSFET source current is decreased to zero from the averaged switching current in section 3. When the MOSFET source current reaches zero, the iW3688 enters section 5, which is called the blanking period. During this period, no switching or current sink is present to minimize power loss and ensure the TRIAC in the dimmer is turned off. When V IN_A falls below 0.184V, the iW3688 enters section 6. In section 6, the current sink circuit is enabled and the sinking current is transitioned from zero to the regulated current level in section 1. At the time when the sinking current reaches the regulated current in section 1, the iW3688 enters section 1. This provides a low impedance load to quickly discharge the capacitance of the driver board. The sinking current naturally goes to zero when the input and RC snubber capacitors (C1, C2, and C3 in Figure 11.1) have been fully discharged.V INI SOURCE1234561Figure 9.4 : Leading Edge Dimmer Mode Operation9.3.2 Trailing-Edge Dimmer ModeIf a trailing-edge dimmer is detected, the iW3688 enters into trailing-edge dimmer mode. The current sink circuit and switching circuit inside iW3688 turn on alternatively.The current sink circuit and switching circuit control during trailing-edge dimmer mode can be split into four operating sections, as shown in Figure 9.5.During section 1, the trailing-edge dimmer requires a low impedance load to charge its internal supply voltage and detect the next zero-crossing. The regulated current of the current sink circuit is set to a high limit while the switching circuit is disabled. When V IN_A exceeds 0.228V, the iW3688 enters into section 2. During section 2, the sinking current is gradually reduced from the regulated current of section 1 to zero. When the sinking current reaches zero, the iW3688Single-Stage Dimmable LED Driversenters section 3. During section 3, both the current sink circuit and the switching circuit are disabled. In section 4, the iW3688 begins to deliver energy to output of the LED driver until the trailing-edge dimmer turns off. After section 4, the iW3688 disables the switching circuit and enters section 1. This provides a low impedance load to quickly discharge the capacitors of the dimmer and driver board.V INI SOURCE12341Figure 9.5 : Trailing Edge Dimmer Mode Operation9.3.3 No-dimmer ModeIf there is no dimmer on the line, the iW3688 operates inno-dimmer mode to optimize power factor and to minimizeharmonic distortion. The current sink circuit is disabled inthis mode and only the switching circuit is used.9.3.4 Controller Power ManagementUnlike most off-line LED controllers, the iW3688 does not rely on auxiliary winding of the main power inductor/transformer to supply the operating current. Instead, it uses Dialog’sproprietary multi-path charging technology to sustain the V CC voltage. Also, a lower nominal V CC level is made possiblewith source switching structure, which reduces the IC power consumption and enables the use of a smaller size V CCcapacitor.Figure 9.6 : V CC Charging CircuitThe iW3688’s operating current is supplied by two paths (shown in Figure 9.6). The first path, called switching charge, re-directs the switching current into the V CC capacitor when MOSFET is turned on. The second path, called sinking charge, re-directs the sinking current into V CC capacitor. When there is no dimmer on the line, only the switching charge is used to achieve high efficiency. When there is a dimmer on the line, both switching and sinking charge are used to ensure V CC is sustained across the entire dimming range.The iW3688 regulates the V CC voltage by adjusting theduration of the charging time. V CC voltage is smoothlyregulated to the nominal level when the iW3688 operatesin no-dimmer mode. When the iW3688 operates in dimmermode, the window for V CC charging is limited. Therefore, the iW3688 charges the V CC voltage to V CC(HIGH) in the charging window. Although V CC voltage droops before next chargingwindow, the iW3688 guarantees V CClevel is always aboveVCC(UVL) when a proper sized V CC capacitor is used.9.4 Output Current Regulation This section provides information about iW3688 output current regulation, which incorporates the Dialog-patentedPrimAccurate TM technology.Single-Stage Dimmable LED DriversFigure 9.7 : Inductor Current Flow in Switching ModeI PI SI SEC T ON T OFFT RT PI PKI PKFigure 9.8 : Cycle-to-Cycle Peak Current RegulationIn iW3688, output current regulation is implemented through peak current control in switching mode. Figure 9.7 and 9.8 show the basic principle of this peak current regulation during the switching mode. During T ON, the main switch Q1 (shown in Figure 9.7) is turned on and the current, I P, flows through the primary side of the buck-boost converter and Q1. I P ramps up linearly and causes energy to build up in the power inductor L1 (shown in Figure 9.7). The iW3688 continuously monitors I SENSE pin voltage, when it reaches V PK (shown in Figure 8.1), it turns off the switching circuit. At this time, I P reaches peak current regulation level I PK (shown in Figure 9.7 and 9.8). After Q1 is turned off, the current in L1 ramps down linearly through D1 (shown in Figure 9.7), until the energy stored in the power inductor is discharged. During this period, the current through L1 flows to the secondary side of the buck-boost/flyback converter, which is called I S.9.4.1 Output Current Regulation in No-dimmer ModeIn no-dimmer mode, V PK is designed to be proportional to the input voltage shape with a lower limit (shown in Figure 9.9). The buck-boost or flyback converter operates in critical discontinuous conduction mode (CDCM) if the switching frequencyof main MOSFET does not exceed the f SW(MAX). Otherwise, if the switching frequency reaches the f SW(MAX), the power converter operates in discontinuous conduction mode (DCM).Input VoltageSOURCEFigure 9.9 : Peak Current Regulation in No-dimmer ModeAs shown in Figure 9.8, the average current of I S in one switching cycle can be expressed by I SEC, whereSECI= 0.5×PK I×RTPT(9.1)where I PK is the peak value of the L1 current, T R is the L1 current ramp-down time, and T P is the entire switching period.The I PK is determined by the voltage generated on the current sense resistor R19 (shown in Figure 11.1): I PK = V PK /R19. Therefore, the equation can be written asSECI= 0.5×PKV×RTPTR19(9.2) In steady state, the average output current is equal to the average I SEC over one half-AC-cycle. Therefore, the average output current can be obtained by averaging equation 9.2 over one half-AC-cycle.The iW3688 regulates the averaged V PK * (Tr/Tp) to be a constant over one AC half cycle. Therefore, the nominal output current I OUT(NOM) can be determined by equation 9.3.Single-Stage Dimmable LED DriversOUT(NOM)I = 0.5××R 190.35V ŋ(9.3)ŋ is the converter efficiency.9.4.2 Output Current Regulation in Dimmer ModeIn dimmer mode, V PK is a fixed value determined by resistor configuration. The switching frequency (f SW ) is also a fixed value based on resistor configuration (see Section 9.5 for details). If the buck-boost or flyback is operating in DCM, a fixed V PK and f SW control can achieve stable I SEC regulation because the energy delivered to the LED is fixed regardlessof input voltage variation. If the buck-boost or flyback is operating in CCM, this stable I SEC regulation cannot be guaranteed. Therefore, the preset V PK and f SW values need to ensure the buck-boost or flyback is operating in DCM. When V IN is low, the iW3688 drops the V PK level to ensure DCM operation (see Figure 9.10). V PKI SENSE V INpin voltageFigure 9.10 : Peak Current Regulation in Dimmer Mode During dimmer mode operation, the output current is regulated with a closed loop control. The reference output current,I OUT(DIM), is calculated by equation 9.4. The instantaneousI SEC current delivered to the output side is accumulatedevery switching cycle when switching is enabled. I OUT(DIM) = I OUT(NOM) × dimming percentage (9.4)When the accumulated instantaneous I SEC current in one half-AC-cycle reaches I OUT(DIM), the iW3688 disables the switching circuit.9.5 Configuration FunctionAt start-up, a current source in the iW3688 drives theconfiguration current I CFG (100µA) into CFG1–CFG4 pin alternatively (shown in Figure 8.1). The iW3688 reads their pinCFG1 pin configuration selects the temperature de-rating start point. CFG2 optimizes the control algorithm for power and NV O *, and CFG2 selects the output current percentage at 70% dimming phase. CFG3 pin configuration selects V PK high limit value at dimmer mode. CFG4 pin configuration selects switching frequency at dimmer mode.By choosing different resistor values for R17, R18, R21, andR22 (shown in Figure 11.1), different configuration values are selected (illustrated in T able 9.1 - 9.4).

Three main functions of this auxiliary winding are: 1. To supply V CC for controller IC; 2. To provide output voltage information;3. To provide magnetic flux information of the inductor. As mentioned in 9.3.4. the iW3688 does not rely on auxiliary winding to charge V CC. In addition, Dialog’s proprietary V SENSE Direct Sensing technology allows the iW3688 to obtain LED output voltage and magnetic flux information without an auxiliary winding.Inside the iW3688, there is a high performance differential current sensing circuit between V D and V CB pin (shown in Figure 9.11). This circuit generates a differential current that is equal to the current flow into V D pin subtracted by the current flow into V CB pin. This differential current is directed to an internal precise resistor, R VSENSE, to generate a voltage called V SENSE. V SENSE is essentially a scaled-down version of V DRAIN minus V CIN, which is the same as the auxiliary winding generated signal.The resistances of R CB and R D are determined by the nominal output voltage, V OUT. In Figure 11.1 R CB refers to R13, and R D refers to R15.)(VSENSERDSENSEV= DRAINV×CINVCBRR (9.5)Single-Stage Dimmable LED DriversDuring the period of T R (shown in Figure 9.8), V DRAIN minus V CIN is approximately equal to V OUT . By making R CB and R D the same, their values can be determined by= D R VSENSE R CB R = ×OUTV SENSEV (9.6)9.7 Protection FeaturesThis section provides information about iW3688 protection features.9.7.1 Output Over-Voltage/LED Open ProtectionThe iW3688 includes a function that protects against anoutput over-voltage.The output voltage is monitored by the V SENSE voltage (refer to Section 9.6). If the V SENSE voltage exceeds V SENSE(OVP), the iW3688 shuts down the switching circuit and current sink circuit (shown in Figure 8.1) immediately. As a result, MOSFET is turned off. After the shutdown of current sink and switching circuits, the iW3688 remains powered, while V CC continues to discharge. In order to avoid over-charging of the output voltage, the iW3688 employs an extended discharge time as described below if V CC does not drop below V CC(UVL). Otherwise, when V CC drops below V CC(UVL), the iW3688 resets itself and then initiates a new soft-start cycle.Under the fault condition, the iW3688 tries to start up forthree consecutive times. If all three start-up attempts fail, theiW3688 enters an inactive mode, during which the iW3688 does not respond to the V CC power-on requests. The iW3688 is activated again after it sees 29 start-up attempts. Typically, this extended discharge time is around three to five seconds.9.7.2 Output Short ProtectionThe iW3688 includes a function that protects against an output short-circuit fault.When output is shorted, V SENSE is below V SENSE(UVP). As aresult, an output short fault is detected. The iW3688 shuts down the switching circuit and current sink circuit (shown in Figure 8.1) immediately. As a result, MOSFET is turned off. After the turn-off of MOSFET, the iW3688 remains powered while V CC continues to discharge. In order to avoid excessive power stress due to auto-restart, the iW3688 employs an extended discharge time as described in section 9.7.1 if V CCdoes not drop below V CC(UVL). Otherwise, when V CC dropsbelow V CC(UVL), the iW3688 resets itself and then initiates a new soft-start cycle.To support applications with high output capacitance, output short protection is not activated during the initial LED currentsoft start period. This allows the voltage to build up in the output capacitor without triggering the protection.9.7.3 Temperature De-Rating and Over-Temperature Protection The iW3688 can detect and protect against over-temperatureevent. The iW3688 utilizes an internal sensor for temperaturemeasurement.When the monitored temperature reaches T DERATE(ST), the maximum output current limit begins to reduce linearly from 100% to 70% of the nominal value until the temperaturereaches T DERATE(FINISH) threshold as shown in Figure 9.12,where T DERATE(FINISH) = T DERATE(ST) + 20°C. At T DERATE(FINISH),the maximum output current limit is clamped to 70%. If the temperature further increases to T OTP(START), the iW3688 shuts down.The iW3688 remains in shutdown mode as long as the monitored temperature is above T OTP(START). If the detected temperature falls below T OTP(START) at anytime, the iW3688 starts up. From T DERATE(FINISH) to T DERATE(ST), the maximum output current limit increases linearly from 70% to 100% as shown in Figure 9.12. The device goes back to normal operation if the sensed temperature falls below T DERATE(ST). This bi-directional operation enables the LED current thermal fold-back instead of an abrupt shut-down of the LED current.The values of T DERATE(ST) and T DERATE(FINISH) can be adjustedthrough the CFG1 pin resistor (refer to Section 9.5).I OUT /I OUT(NOM)%T DERATE(ST)T DERATE(FINISH)T OTP(START)Figure 9.12 : Temperature DeRating and OTP9.7.4 Over-Current Protection Over-current protection (OCP) is a feature that is built into the iW3688.。

MIC3263评估板六通道WLED驱动器说明书
MIC3263 Evaluation BoardSix-Channel WLED Driver for Backlighting Applications withFlicker-Free DimmingBringing the Power to Light™MLF and Micro LeadFrame are registered trademarks of Amkor Technology, Inc.General DescriptionThis evaluation board (EVB) is designed for the MIC3263. The MIC3263 is a high-efficiency Pulse Width Modulation (PWM) boost switching regulator that is optimized for constant-current WLED driver backlighting applications. The MIC3263 drives six channels of up to ten low-power WLEDs per channel. Each channel is matched in current to within ±3% for constant brightness across the screen and can be programmed from 15mA to 30mA.The MIC3263 provides a very flexible dimming control scheme with high accuracy and noise immunity. The dimming frequency can be set to any value between 100Hz and 20kHz by an external resistor. The dimming ratio is determined by the duty-cycle of a dimming ratio control input signal and can be set to one of 16 levels with a minimum ratio of 1%. The LED dimming current is set by an external resistor to allow programming of LED current between 15mA and 30mA.The dimming ratio of the MIC3263 is fixed to 16 logarithmic levels to better match the sensitivity of the human eye. Each of the dimming levels has hysteresis to avoid skipping between levels resulting in Flicker-Free operation.The MIC3263 has a programmable PWM switching frequency from 400kHz to 1.8MHz to allow small inductor sizes. The 6V to 40V wide-input voltage range of MIC3263 allows direct operation from 6V or high cell count Li-Ion batteries commonly found in notebook computers.PrecautionsThe MIC3263 evaluation board operates as a boost converter, which requires the output voltage to be greater than the input voltage. Connect a PWM dimming signal to the DRC pin. The DRC pin needs an input signal to operate.Requirements1. Voltage source capable of supplying 10W2. Load: Six LED strings3. Scope4. Function generator for PWM DimmingGetting Started1. Set the LED current of all six channels by one resistorR ISET (noted as R9 on the EVB). Use 2k Ω for 30mA and 3k Ω for 20mA. Use the following equation to find R ISET :LED60R =ISET I Ω2. Connect six strings of LEDs from LED out to LED-RTN. Each one of the six LED strings needs to connect to one of the LED RTN. The cathode end of each LED string connects to one of the six LED RTN pins. The anode end of all the LED strings connects to LED OUT (V OUT ). The number of LEDs in each string should be from 4 to 10.3. Connect 12V (or other input voltage) to V IN and GND.4. Use a current probe to measure the load current andmonitor the switch node with a scope to view the switching waveform 5. PWM Dimming:a. Connect a function generator to thedimming input (DRC pin) 0V to 5V at 100Hz to 40kHz.b. Adjust the duty-cycle of the functiongenerator for PWM dimming. The MIC3263 converts the duty-cycle at the DRC to one of sixteen dimming ratios (DR) according to Table 1.c. Follow the power-on sequence to ensureall channels turn on.d. The EVB is set for 30mA LED current. Fora different LED current, change R9 using the given equation.Power-On SequenceV IN needs to be present before PWM pulses are applied to the DRC pin. Some channels may not turn on if the power-on sequence is not followed. This may be the case if the circuits that monitor the IO pins see transients during the turn on-time and may interpret voltage spikes during turn-on as a fault, preventing that channel from turning on. When a channel is off, its IO pin is at high impedance.It is best to follow the sequence:1. V IN2. PWM dimming at DRC3. Enable highMODEThis selects the internal PWM dimming frequency range. When MODE is low, the PWM dimming frequency range is 100Hz to 2kHz and it selects low-frequency (LF) mode. When MODE is high, the PWMD frequency range is 1.5kHz to 20kHz and it selects high-frequency (HF) mode.DFSDFS stands for Dimming Frequency Select. The dimming frequency of the LEDs is different than the input dimming frequency at the DRC input. The MIC3263 uses an internal dimming frequency. This internal dimming frequency is programmable by an external resistor to ground R DFS (R8).When using internal dimming the range is determined by the MODE pin and the actual frequency is determined by R DFS. Connect a resistor-to-ground to select a dimming frequency.Use the following equations to determine the value for R DFS:R DFS(kΩ) = −20 × f DIM(kHz) + 432 (HF Mode)R DFS(kΩ) = −335 × f DIM(kHz) + 433 (LF Mode)For direct dimming control, connect DFS to V DD and use the MODE pin for the input dimming pulse. This method by passes the internal dimming control and allows for dimming control by the external PWM pulse. OVPThis is the over-voltage protection monitor. Also this is the feedback signal that connects to the error amplifier input. The output voltage that the OVP will trigger is set according to the following equation. Using the values for this example gives a max output voltage of:V OVP = 2.4 × (R1+R2)/R1 = 38VInternal PWM DimmingThe duty-cycle of the PWM pulse applied to the DRC input is converted to 16 log levels. This logarithmic dimming is a unique feature of the MIC3263 which better matches the sensitivity of the human eye compared to linear dimming. The DRC duty-cycle to DR duty-cycle conversion is shown in Table 2.DRC DutyCyclePWM Dimming Ratio (DR)DR = 10(N − 1) / 7N%%0 0 01 6.25 1.02 12.5 1.43 18.75 1.94 25 2.75 31.25 3.76 37.5 5.27 43.75 7.28 50 109 56.25 1410 62.5 1911 68.75 2712 75 3713 81.25 5214 87.5 7215 93.75 100Table 1.
