It applies advanced digital control technology to detect the dimmer type and phase, which provides dynamic impedance to interface the dimmer and control the LED brightness at the same time. The iW3617 uses iWatt’s unique digital Flickerless TM technology to eliminate visible flicker in the entire dimming range and minimize low frequency output ripple current.With advanced dimmer detection technology, the iW3617 can operate with most wall dimmers including leading-edge dimmers (R-type or R-L type) and trailing-edge dimmers (R-C type). In addition, the iW3617’s cycle-by-cycle waveform analysis technology allows fast dimmer setting response. When no dimmer is on the line, the iW3617 optimizes the power factor and minimizes the current harmonic distortion to the AC line.The iW3617 operates the main power converter that delivers constant current to the LED load in quasi-resonant mode to provide high power efficiency and minimize electro-magnetic interference (EMI). It uses iWatt’s patented PrimAccurate TM 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 eliminating the need for an opto-coupler.The iW3617 minimizes the external components count by simplifying the EMI filter with iWatt’s EZ-EMI® technology. The intelligent dimmer detection technology eliminates the need for a high-power bleeder. Additionally, the digital control loop of the iW3617 maintains stable overall operating conditions without the need for loop compensation components.●Dimmable LED retrofit lamps up to 25W●Dimmable LED ballast and luminaries up to 25WHigh Power Factor Dimmable LED DriversBooster ConverterFlyback ConverterFigure 3.1 : iW3617 Simplified SchematicHigh Power Factor Dimmable LED DriversiW3617High Power Factor Dimmable LED DriversNotes:Note 1. ψJB [Psi Junction to Board] provides an estimation of the die junction temperature relative to the PCB surfacetemperature.

It analyzes the rectified AC waveform and determines whether a dimmer is connected on the line. If no dimmer is connected, the block switches the boost BJT (B DRV pin) for PFC and stores the energy in the boost output capacitor. The PFC operation is based on the input voltage (V IN pin), the boost output voltage (V CB pin), and the magnetic flux status of the boost inductor (BV SENSE pin). If a dimmer is connected, the block detects the type of dimmer by analyzing the shape of the rectified AC waveform (V IN pin). It then provides dynamic impedance to interface the dimmer by driving the boost BJT (B DRV pin). The purpose is to match the load requirement of the dimmerwhile storing the energy in the boost output capacitor. To provide accurate impedance, the gain (β) of the boost BJT is calibrated (BI SENSE pin). The block also measures the dimmer phase conduction angle to determine the dimming level (refer to Section 9.2 for details).The LED current regulation and dimming control block control the flyback or buck/boost converter as the second power stage (shown in Figure 3.1). It switches the flyback MOSFET (F DRV pin) to supply constant current to LED load from the energy stored in the boost output capacitor. The constant current regulation algorithm is based on the information of the transformer primary-side peak current (FI SENSE pin) and magnetic flux status of transformer (FV SENSE pin). The block also dims LEDs by adjusting the output current based on dimmer phase conduction angle provided by power factor correction and dimmer interface block. (refer to Section 9.2 for details).V IN BV SENSEV CCV T BI SENSEF DRVV CBCFGB DRVFV SENSE FI SENSEPGND AGNDASUHigh Power Factor Dimmable LED Drivers9.1 System Start UpThis section provides information about iW3617 system start up, which include the IC startup, wall dimmer detection, and the LED current soft start.9.1.1 IC StartupWhen AC voltage is applied, the boost output capacitor in (C3 in Figure 11.1) is charged to the peak of line voltage. ASU pin is open by default so that ASU BJT (Q3 in Figure 11.1) is turned on and V CC capacitors (C8 and C9 in Figure 11.1) is charged through ASU resistor (R9 in Figure 11.1) and ASU BJT. When the V CC voltage reaches start-up threshold V CC(ST), the iW3617’s control logic is activated and the IC starts up. The ASU pin is kept open and the ASU circuit continues charging V CC until 50ms after the main flyback converter starts.Start-up SequencingFigure 9.1 : Start-up Sequencing 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 calledleading-edge dimmer (shown in Figure 9.2). Otherwise it is called trailing-edge dimmer (shown in Figure 9.3). Normallyspeaking, leading-edge dimmer is TRIAC based (R-type,RL-type); trailing-edge dimmer is MOSFET or IGBT based(RC-type).AC line before Wall-dimmerAC line after Wall-dimmerFigure 9.2 : Leading-Edge Wall Dimmer WaveformsAC line after Wall-dimmerAC line before Wall-dimmerFigure 9.3 : Trailing-Edge Wall Dimmer WaveformsThe dimmer detection stage occurs in the iW3617 immediately after IC starts up. The iW3617 is driving the boost BJT (Q2 in Figure 11.1) constantly on to do currentsinking during the wall dimmer detection. The purposes of current sinking at startup are: ●Calibrate the sinking current to 200mA to compensatefor the BJT gain variation. This 200mA current sinking is used to latch the leading-edge dimmer during the phase-cut in normal operation. ●Place a low impedance resistance on the AC line toaccurately detect whether a dimmer is connected and the type of dimmer connected.The dimmer type can be determined by looking at the derivative of the input AC voltage. A large positive derivative value indicates a leading-edge dimmer. Otherwise, trailing- edge dimmer or no dimmer is detected.High Power Factor Dimmable LED Drivers Once the dimmer type is determined, the iW3617 needs toqualify the AC input signal before delivering current to theLED load. If under any condition the iW3617 does not seethe peak of VIN signal above VIN_ST(MIN)for two consecutiveAC half-cycles or the AC line frequency is out of range, the AC input signal is considered as unqualified. The iW3617 will continuously monitor the AC input signal until it sees a qualified AC input signal and then starts to deliver currentto the LED load. Or if the VCC drops under VCC(UVL)in thisprocess, the iW3617 will reset and the VCC voltage willcharge up again for a fresh start-up.9.1.3 LED Current Soft-StartAfter the iW3617 qualifies the AC input signal, the flyback converter will immediately start to deliver constant current to the LED load. A soft-start algorithm is applied to the flyback converter to gradually ramp up the LED current, thus reducing the stress on the LEDs. If no dimmer or a trailing-edge dimmer is detected, the output current will ramp up to the target current level within several AC half cycles. If a leading-edge dimmer is detected, the ramp up of the LED current is slower to avoid current over-shoot or under-shoot. This is because the leading-edge dimmer’s phase conduction angle is usually not stable when the load on the dimmer is light.If a dimmer is connected, the boost converter will start immediately into leading-edge or trailing-edge mode operation (refer to Section 9.31 and 9.32 for details) to interface the dimmer. If no dimmer is connected, the boost converter will start PFC operation (refer to Section 9.33 for details).9.2 Phase Measurement and DimmingCurveThis section provides information about iW3617 phase measurement and dimming curve.9.2.1 Phase MeasurementDimmer phase conduction angle is measured every AC half cycle. Dimmer phase is determined by the time periodthat VIN stays above the zero-crossing threshold (tCROSS) asshown in Figure 9.4. The threshold is 140mV.V CROSStPERIODtCROSSFigure 9.4 : Dimmer Phase MeasurementAnd the dimmer phase ratio (D ratio) is calculated as:Dimmer Phase Ratio (D ratio) = tCROSS/tPERIOD(9.1)The tPERIODis the period of AC half cycle, which is measured by the time span between the moments that VINrises above the 140mV reference in two consecutive AC half cycles. If the D ratio is above 90%, the iW3617 considers no dimmer is on the line.9.2.2 Dimming CurveThe iW3617 dims the LED by reducing the output current to a certain percentage of the LED current level when there is no dimmer, which is called dimming percentage. A mapping between the D ratio and the dimming percentage is pre-determined in the iW3617. There are two different mapping options, or dimming curves, that can be selected with the CFG pin (refer to Section 9.5 for details). Both dimming curves fall within the limits of the NEMA SSL6 standard (as shown in Figure 10.6). The iW3617 updates the dimming percentage based on the D ratio measurement every AC half cycle to ensure fast dimmer response.9.3 Dimmer Interface and Power FactorCorrection Block OperationThis section provides information about iW3617 dimmer interface and power factor correction block’s operation, which includes leading-edge dimmer mode, trailing-edge dimmer mode, no dimmer mode, and transition between these operation modes.9.3.1 Leading-Edge Dimmer ModeIf a leading-edge dimmer is detected on the line, the boost converter is operated in leading-edge dimmer mode. This mode provides dynamic impedance matching for the leading-edge dimmers. The leading-edge mode operation can be split into five intervals, as shown in Figure 9.5.During interval 0, 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 boost BJT (Q2 in Figure 11.1) is driven in current sink mode to provide such low impedance load. When the TRIAC inside the dimmer is fired, the operation enters interval 1. Interval 1 is a short period of time after the TRIAC fires. The boost BJT is kept in current sink mode to provide 200mA latching current for the TRIAC. Then the operation enters interval 2. The boost BJT is in switching mode during interval 2. Interval 2 ends at 90˚ of the phase angle. During Interval 2, the iW3617 boosts the energy into the boost output capacitor and provides the holding current of the TRIAC at the same time. Interval 3 is a 400µs blanking time to ensure the TRIAC turns off after enough energy is boosted into the boost output capacitor. Then the operation enters interval 4 in which the boost BJT is in light duty-cycle switching mode to discharge the EMI filter capacitors of the LED driver.9.3.2 Trailing-Edge Dimmer ModeIf a trailing-edge dimmer is detected on the line, the boost converter is operated in trailing-edge dimmer mode. This mode provides dynamic impedance matching for trailing-edge dimmers. The operation can be split into four intervals, as shown in Figure 9.6.During interval 0, the boost BJT is driven in current sink mode to reset the dimmer with a low impedance load. Interval 1 begins as the VINrises above the zero crossing reference. The boost BJT is driven in switching mode to boost energy into the boost output capacitor. Then interval 2 starts at a short period of time before the phase-cut edge to increase the switching duty cycle as a transition state between interval 1 and interval 3. Interval 3 begins right at the phase-cut edge. The boost BJT switches with four times of the duty cycle as in interval 1 to quickly discharge the EMI capacitor inside the dimmer so as to ensure the accurate phase.9.3.3 No Dimmer Mode (PFC Operation)If there is no dimmer on the line, boost converter is operated in PFC mode for optimal power factor and minimum harmonic distortion. The iW3617 switches the boost BJT in valley mode switching to minimize the switching loss and EMI. Input current will follow the input voltage as shown in Figure 9.7.V AC InductorCurrentInputCurrentFigure 9.7 : No Dimmer Boost Mode OperationThe iW3617’s PFC algorithm is based on fixed on-time switching with the compensation of dead-time after the boost inductor resets. The dead-time is measured from the moment that boost inductor resets (determined by BVSENSEHigh Power Factor Dimmable LED Driverspin) to the following boost BJT turn-on moment (determined by B DRV pin). To maximize the power efficiency, the boost output capacitor voltage is set to be 30V above the peak AC line voltage for 230V AC input and 15V above for 120V AC input.9.3.4 Transition Between Operation Modes The iW3617 constantly monitors the derivative of the V IN signal every AC half cycles to ensure the boost converter’s operation is in the correct mode. The mode of the operation is continuously updated based on the latest detected dimmer type.The iW3617 also monitors dimmer existence by looking atthe D ratio. If the D ratio is greater than 90% at any time, theboost converter will enter the No Dimmer mode immediately. 9.4 LED Current Regulation andDimming Control Block OperationThis section provides information about iW3617 LED current regulation and dimming control block operation.9.4.1 Cycle-by-Cycle LED Current Regulation The LED current regulation and dimming control block incorporates the iWatt-patented PrimAccurate TM technology. Constant current is guaranteed regardless of the input voltage (boost output capacitor voltage) or the output voltage (LED load forward voltage) of the flyback converter. Figure 9.8 shows the basic principle of this constant current regulation algorithm.I PI Ot ONt OFFt SFigure 9.8 : Constant Current RegulationThe flyback converter is operated in critical discontinuousconduction mode (CDCM). When the flyback MOSFET (Q1 in Figure 11.1) turns on, the transformer primary winding current ramps up linearly and energy builds up in the transformer. The iW3617 turns off the MOSFET when the primary winding current reaches the peak current regulation level. At this moment, the transformer maintains the magnetic flux so that the energy in the transformer generates the secondary winding current that equals to the peak primary winding current multiplied by primary-secondary turns-ratio. Then the secondary winding current ramps down linearly until all the energy in transformer is discharged. After the energy in the transformer is discharged, the iW3617 starts the next switching cycle. The LED load current is the average of the saw-tooth shaped secondary winding current.The LED load current can be determined by an equation asshown below.I OUT = 0.5 × N TR × I PK × T R / T P(9.2)where I PK is the peak of primary winding current. N TR is the primary-secondary turns ratio. T R is the secondary winding current ramp-down time, or the transformer reset time. T P isthe entire switching period.The I PK is determined by the voltage generated on thecurrent-sense resistor: I PK = V PK / R S . Therefore, the equation can be written as:I OUT = 0.5 × N TR / R S × (V PK × T R / T P )(9.3)The iW3617 measures T R and T P on a cycle-by-cycle basis and controls V PK so that the K CC = V PK × T R / T P is always a constant. The K CC is an internally defined constant that equals to 0.7V. Therefore, the I OUT can be determined by the turns-ratio and current sense resistor at the design time of the application circuit. 9.4.2 Dimming ControliW3617 has two dimming scheme options which can be selected by the CFG pin (refer to Section 9.5 for details). The first one is pulse width modulation (PWM) dimming. The second one is constant current pulse frequency modulation (CC-PFM) dimming. ●PWM Dimming ModeFrom 100% to 25% dimming percentage, the iW3617 employs the same constant current regulation algorithm as described in section 9.4.1 while reducing the K CC constant. As a result, the I OUT will proportionally decrease as the K CC decreases. In this process, the switching frequency of the flyback converter will increase. The maximum switching frequency is clamped at 200kHz.At 25% dimming percentage, the iW3617 will clamp the K CC value and switch to the 630Hz PWM dimming. FurtherHigh Power Factor Dimmable LED Driversdimming is achieved by only activating the flyback converter during a certain percentage of time in every 630Hz period. ●CC-PFM Dimming ModeFrom 100% to 25% dimming percentage, the iW3617 operates in the same K CC -reduction dimming method as described in PWM dimming, except that the frequency clamp changes linearly from 200kHz at 100% dimming percentage to 50kHz at 25% dimming percentage. Below 25% dimming percentage, the iW3617 will switch to the CC-PFM mode, which keeps the V PK a constant and increase the T P to achieve further dimming.9.5 CFG PinThe CFG pin is used to select between the two dimming modes (described in Section 9.42) and the two dimming curves (see Figure 10.6). At startup, the CFG pin outputs I CFG after V CC reaches V CC(ST). The iW3617 reads the CFG pin voltage after 40µs. The dimming curve and dimming mode are selected by connecting a resistor with different values to the CFG pin as shown in Table 9.1CFG Option NumberCFG Pin ResistorDimming Curve Number (Fig. 10.6)DimmingControlValueTolerance120k W ≤ 5%1PWM 212.7k W ≤ 5%1CC-PFM 38.87k W ≤ 5%2PWM 45.62k W≤ 5%2CC-PFMTable 9.1 CFG Pin Resistor9.6 Protection FeaturesThis section provides information about iW3617 protectionfeatures.9.6.1 Output Over-Voltage/LED Open ProtectionThe iW3617 includes a function that protects against an output over-voltage.The output voltage is monitored by the FV SENSE pin. The ratio between the FV SENSE pin voltage and output voltage is equal to the transformer auxiliary to secondary winding turns-ratio multiplied by the FV SENSE resistor divider ratio (R20, R21 in Figure 11.1). If the voltage at the FV SENSE pin exceeds V SENSE(MAX), the iW3617 shuts down immediately. After the shutdown, the iW3617 remains powered which discharges the V CC . In order to avoid over-charging the output voltage, the iW3617 employs an extended discharge time as described below. Under the fault condition, the iW3617 tries to start up for three consecutive times. If all three start-up attempts fail, the iW3617 enters the inactive mode, during which the iW3617 does not respond to the V CC power-on requests. The iW3617 is activated again after it sees 29 start-up attempts. The iW3617 can also be reset to the initial condition if the V CC is completely discharged. Typically, this extended discharge time is around three to five seconds, and it allows the iW3617 to support hot-plug LED modules without causing ouput over-voltage while maintaining a quick recovery.9.6.2 Output Short ProtectionThe iW3617 includes a function that protects against an output short-circuit fault.If the voltage at the FV SENSE pin is below 0.228V, the iW3617 shuts down immediately. After the shutdown, the iW3617 remains powered, which discharges the V CC . In order to avoid excessive power stress due to auto-restart, the iW3617 employs an extended discharge time (as described in Section 9.61).To support applications with high output capacitance, output short protection is not activated in the initial LED current soft start period. This allows the voltage to build up in the output capacitor without mis-triggering the protection.9.6.3 Over-Temperature ProtectionIf an NTC thermistor is connected between the V T pin and the GND, the iW3617 is able to detect and protect against an over-temperature event.The iW3617 provides an I VT to the V T pin and detects thevoltage on the pin. Based on this voltage, the iW3617 canmonitor the resistance of the NTC thermistor, which is related to the temperature of the thermistor. As the V T pin voltagereduces, the iW3617 reduces the power in boost and flybackconverter.High Power Factor Dimmable LED DriversFigure 9.9 : V T Pin Voltage vs. % of Nominal Output CurrentWhen the V T pin voltage reaches V P-LIM(HI) the output current begins to reduce linearly from 100% to 20% as shown in Figure 9.9. At V P-LIM(LO) the output current will be clamped to1%. If the V T pin voltage further decreases to below V SH_TH , the iW3617 will shut down.The iW3617 will remain in shut-down mode as long as the V T pin voltage is below V SH_TH . If the V T pin voltage rises above V SH_TH at any time, the device will start up and the output will be clamped at 1%. Once the V T pin voltage reaches V P-LIM(LO), the output current will increase to 20%. From V P-LIM(LO) to V P-LIM(HI), the output current will increase linearly from 20% to 100% as shown in Figure 9.9. Finally, the device will go back to normal operation when the V T pin voltage rises above V P-LIM(HI).This bi-directional operation of the V T pin enables the LED current thermal foldback instead of an abrupt shut-down of the light. As the output power decreases under the mild over-temperature condition, the amount of heat generated by the LED also decreases, which reduces the possibility of furthertemperature rise of the system.9.6.4 Over-Current ProtectionOver-current protection (OCP) is a feature that is built into theiW3617.With the FI SENSE pin the iW3617 is able to monitor the primary peak current of the flyback converter. This allows for cycle-by-cycle peak current control and limit. When the primary peak current multiplied by the FI SENSE sense resistor(R15 in Figure 11.1) is greater than V OCP(FLYBACK), over-current is detected and the iW3617 immediately turns off the gate drive until the next cycle. The F DRV pin sends out switching pulse in the next cycle, and the switching pulse continues if the V OCP(FLYBACK) is not reached; or, the switching pulse turns off again if the V OCP(FLYBACK) is still reached.The BI SENSE pin provides the same protection mechanism for the boost converter. The BI SENSE OCP threshold is V OCP(BOOST) in no dimmer or trailing-edge dimmer mode. The BI SENSE OCP threshold is 1.5V in leading-edge dimmer mode.9.6.5 Sense Resistor Short ProtectionIf the FI SENSE sense resistor is shorted there is a potential danger of the over-current condition not being detected. Thus the iW3617 is designed to detect this sense-resistor short fault. If the voltage on the FI SENSE pin is belowV RSENSE(FLYBACK) after 15.6µs of turning on, the sense-resistorshort protection is triggered and the iW3617 shuts down immediately. After the shutdown, the V CC is dischargedsince the iW3617 remains powered. The iW3617 employsan extended discharge time (as described in Section 9.61) before restart. If the BI SENSE resistor is shorted, the iW3617 cannotdetermine the emitter current of the boost BJT, which can ultimately result in the boost BJT exceeding its safeoperating area. Thus the iW3617 is designed to detect this boost sense-resistor short fault. When the iW3617 detects a boost-sense-resistor short fault at the detection cycle, the iW3617 shuts down immediately. In the leading-edge and trailing-edge modes, the detection cycle is the zero crossing period in an AC half cycle. If there is no dimmer on the line, the only detection cycle is at start-up. After the shutdown,the V CC is discharged since the iW3617 remains powered. To prevent over-stress on the boost circuit components, theiW3617 employs an extended discharge time (as described in Section 9.61) before restart. 9.6.6 Boost Inductor Short-Protection The boost inductor is protected from short condition in no dimmer mode. If the BV SENSE pin is not able to see the reset of the boost inductor, the boost inductor short is detected. The iW3617 will short down immediately.9.6.7AC Input and Boost Output Over-Voltage ProtectionThe iW3617 supports the over-voltage protection of AC input and boost output voltage. If the V IN pin voltage is higher than V IN_OVP for continuous 2ms within every 16ms period, and this condition lasts for eight consecutive AC half cycles, the iW3617 shuts down both the boost and flyback converters. After the shutdown, the V CC is discharged since the iW3617 remains powered.When V CC drops below below V CC(UVL), the iW3617 resets itself and then initiates a new soft-start cycle.。
Keysight Triple Output E36300 Data-Sheet
E36300 SeriesTriple Output Bench Power SupplyD A T A S HE E TPower Your Next InsightFor more than 50 years, Keysight Technologies, Inc. DC powersupplies have been changing the way engineers prove their design, understand the issues, and ensure product quality. On the bench, the triple output E36300 series is ready for your application. With low output ripple/noise and accurate voltage/current measure-ment, you can test with confidence—and power your next insight.Get more for lessThe triple output E36300 Series gives you the performance of system power supplies at an affordable price. There are three models available in the series:E36311A: This 80 W model offers a simplified user experience and the lowest price of the series. Some of the key differences include channels 2 and 3 are configured in tracking mode only, USB interface only, 2-wire sensing. This model does not offer data logging, output sequencing, list mode and auto parallel/serial voltage or current boost.E36312A: This 80 W model offers the complete feature set. Chan-nel 2 and 3 are electrically isolated independent channels. Some of the key extended features include; USB, LAN and optional GPIB interface, 2 or 4-wire sensing, data logging, output sequencing, list mode, and auto parallel/serial.E36313A: This 160 W model offers twice the current of the other models with the same extended feature set as the E36312A model.FeaturesClean, reliable power–Low output ripple and noise–Excellent programming/readback accuracy –Excellent line/load regulation: 0.01% –2-wire or 4-wire remote sense–Over voltage, over current, and over temperature protectionConvenient benchtop capabilities–Three independent power supplies in one box –Low acoustic noise–Auto series/parallel connections –Front and rear output terminalIntuitive and easy to use interfaces–4.3-inch LCD color display –Color-coded channels–Individual knobs for voltage and current –E3631A code compatible–LAN (LXI), USB and GPIB (optional)Advance characterization–Data logging–Output sequencing –LIST mode–Low current range measurementE36311A 80W Triple Output Power Supply,6V, 5A & ±25V, 1A, USB E36312A 80W Triple Output Power Supply,6V, 5A & 2X 25V, 1A, USB, LAN E36313A 160W Triple Output Power Supply,6V, 10A & 2X 25V, 2A, USB, LANConfidently supply your DUT with clean, reliable powerAccurate voltage/current programming and readback capability provide excellent control on the power supply and power mea-surement. The low, normal mode noise specifications assure quality power for precision circuitry applications, enabling you to power your design with confidence. Besides the 0.01% load and line regulation, the E36300 Series can also maintain a steady output when power line and load changes occur, giving you more peace of mind. The built-in capability to measure low range current (<20mA) reduces the need for an external multimeter and simplifies the setup.Improved measurement accuracy with 4-wire sensingTo further improve the voltage regulation and measurement accuracy of the DC outputs, the E36312/13A models offer 4-wire sensing capability, also called remote sensing, on each of the rear terminals. Remote sensing permits the output module to monitor and regulate its output voltage directly at the DUT input terminals instead of the power supply’s output terminals. Four wire sensing is particularly useful for compensating for the voltage drops in the power leads when using the higher output currents generated by the E36313A. For convenience, an internal relay controls switching between 2-wire mode (local sensing) and 4-wire mode (remote sensing) thus eliminating the need for shorting bars or jumpers commonly found on other bench power sources. Keysight understands that protecting your DUT is crucial to limit testing, so the E36300 Series includes Over Voltage Protection (OVP), Over Current Protection (OCP), and Over Temperature Protection (OTP) to prevent damage.Reduce space, cost and noise with convenient benchtop capabilitiesAll three outputs on the E36300 Series can be turned on and off independently, so you are essentially getting three power supplies in one instrument which saves cost on maintenance. It also saves space on the bench as you can power up multiple analog/digital circuitries or devices with a single instrument.For even more voltage or current, Channel 2 and Channel 3 of the E36312/13A set series or parallel mode on the front panel to double the output voltage (up to 50 V) or current (up to 4 A) respectively.The E36300 Series is one of the quietest power supplies in its class. It automatically lowers the fan speed under the load/ no load condition to eliminate annoying acoustic noise through a thermal control circuit. At a typical noise level of less than 26 dBA under no load condition and less than 50 dBA under full load condition, it allows you to work in a quiet and undisturbedenvironment.Figure 1. On E36312A or E36313A set 2-wire or 4-wire sensing for output 1 in justone clickFigure 2. Auto-series operation to double the output voltageSimplify set up and operation with an intuitive and easy-to-use front-panel interface and connectivityThe 4.3-inch LCD color display shows the voltage and current of all three channels with different views. Color coding of the knobs, display and binding posts helps avoid setup and connection errors. Two individual knobs for voltage and current with rotary encoder control for precise setting and keypad allows quick adjustments and configurations in less time.The E36312/13A also offer rear output terminals for easy wiring, which is ideal for both bench and system setup.All models support operation via, SCPI (standard commands for programmable instruments) programming language, IVI (interchangeable virtual instruments) driver, Web Browser or BenchVue. The E36300A series is code compatible with the E3631A to assist in migration to a more modern power supply.The E36311A ships standard with USB and the E36312/13A withboth LAN and USB (GPIB optional).Figure 3. The E36312A and E36313A have rear output terminals for all channelsFigure 4. View all three outputs simultaneously.Figure 5. View details of a single channel including the measured power, OVP/OCPcondition, and delays.Figure 6 Control the power supply from anywhere with the web graphical user interface which is identical to operating the instrument front panel.BenchVue software applicationBenchVue Control and VisualizationBenchVue software for the PC makes it simple to connect, control, and view Keysight power supplies simultaneously with other Keysight bench instruments without programming.–Visualize the output of multiple power supplies simultaneously–Log data, capture screen shots, and save a system state–Recall a past state of your bench to replicate results –Export measurement data in desired format fast –Quickly access manuals, drivers, FAQs and videos –Monitor and control your bench from mobile devicesData logging and output sequencing for increased productivity (available on E36312/13A models only)Emulating the normal behaviors of your power subsystems early in the design process, including controlling multiple power supply voltage sequences, measuring wide dynamic ranges of current, and varying the speed of the power supply voltage to reflect real circuit characteristics is critical your design’s success. The E36312/13A offer additional capabilities for emulating and analyzing power behaviors.Logging data is key to reviewing test set ups and repeating test conditions. The E36312/13A simultaneously logs data on all three DC outputs, both voltage and current measurements, spaced by a programmable sample period, to the large color display and a file. Export the data logger display in PNG, BMP file formats or export the time stamped data as a CSV file for reports and documentation. The built-in battery backup real time clock allowsfor proper time-stamping of logged data.Figure 7. In Data Logger View, you can log data on multiple traces. Here the voltageof output 1, output 2 and output 3 are captured over 30 secondsFigure 8. Output sequencing and Output LIST mode settingSimulate power problems or normal operation with either sequencing or list mode. Sequence each channel on the E36312/13A models individually to turn on or turn off with adelay. Generate complex sequences of output changes with rapid, precise timing synchronized with internal or external signals by using LIST mode.Feature E36311A 80 W Economy Model E36312A 80 WFull-Featured Model E36313A 160 WHigh Current Model ChannelsTracking Only Fully IndependentFully IndependentElectrically isolated channels Not available Standard Standard Remote Sensing 2 Wire Only 2 and 4-Wire 2 and 4-Wire Auto series/parallel Not available Standard Standard Data Logging Not available Standard Standard Output Sequencing Not available Standard Standard List ModeNot available Standard Standard USB port for data logging/storage Not available Standard Standard Digital triggers Not available Standard Standard Rear output terminalsNot available Standard Standard Earth ground reference at rear panel Not available Standard Standard Digital I/O port Not availableStandardStandardConnectivityUSB USB and LAN Standard,GPIB OptionalUSB and LAN Standard,GPIB OptionalRecessed binding posts Optional Optional Optional Keypad locking Standard Standard Standard Benchtop lockStandardStandardStandardWhich Model Is For You?There are three models in the E36300 Series.

Digital Active Thermopile Array
16x4 IR array
General Description (continued)
The results of the infrared sensor measurements are stored in RAM: • 16-bit result of IR measurement for each individual sensor (64 words) • 16-bit result of PTAT sensor Depending on the application, the external microcontroller can read the different RAM data and, based on the calibration data stored in the EEPROM memory, compensate for difference between sensors to build up a thermal image, or calculate the temperature at each spot of the imaged scene. These constants are accessible by the user microcontroller through the I2C bus and have to be used for external post processing of the thermal data. This post processing includes: • Ta calculation • Pixel offset cancelling • Pixel to pixel sensitivity difference compensation • Object emissivity compensation • Object temperature calculation The result is an image with NETD better than 0.5K at 1Hz refresh rate. The refresh rate of the array is programmable by means of register settings or directly via I2C command. Changes of the refresh rate have a direct impact on the integration time and noise bandwidth (faster refresh rate means higher noise level). The frame rate is programmable in the range 0,5Hz…512Hz and can be changed to achieve the desired trade off between speed and accuracy. The MLX90620 requires a single 3V supply (±0,6V). The customer can choose between 3 operating modes: • Normal. In this mode the device is free running under control of the internal state machine. Depending on the selected refresh rate Fps (Frame per second) the chip is constantly measuring both IR and PTAT and is refreshing the data in the RAM with specified refresh rate; • Step. This mode is foreseen for synchronization with an external micro-controller. The internal state machine is halted. If the command ‘StartMeas’ is received via the I2C bus, a single measurement of all IR and PTAT sensors will be done, then the chip will return in wait state. When in wait state the data in RAM can be read. The MLX90620 is factory calibrated in wide temperature ranges: • -40…85 ˚C for the ambient temperature sensor • -50…300 ˚C for the object temperature. Each pixel of the array measures the average temperature of all objects in its own Field Of View (called nFOV). It is very important for the application designer to understand that the accuracy of the temperature measurement is very sensitive to the thermal equilibrium isothermal conditions (there are no temperature differences across the sensor package). The accuracy of the thermometer can be influenced by temperature differences in the package induced by causes like (among others): Hot electronics behind the sensor, heaters/coolers behind or beside the sensor or by a hot/cold object very close to the sensor that not only heats the sensing element in the thermometer but also the thermometer package. This effect is especially relevant for thermometers with a small FOV as the energy received by the sensor from the object is reduced

Samples of MAX3620B (1.00ns delay),MAX3620C (1.25ns delay), and MAX3620D (1.50nsdelay) are also included to be installed by the user._______________Ordering InformationPART TEMPRANGE ICPACKAGEMAX3620AEVKIT -40°C to +85°C 6 TDFNMAX3620BEVKIT -40°C to +85°C 6 TDFNMAX3620CEVKIT -40°C to +85°C 6 TDFNMAX3620DEVKIT -40°C to +85°C 6 TDFN_____________________Selector GuidePART PKG CODE TOP MARKMAX3620A T633-2 AJXMAX3620B T633-2 AIYMAX3620C T633-2 AIZMAX3620D T633-2 AJA______________________Component ListDESIGNATION QTY DESCRIPTIONJ1, J2, J3, J4, J5,J6 6 SMA connectors, edgemountU1 1 MAX3620AETT 3mmX3mm6 TDFN1 MAX3620BETT 3mmX3mm6 TDFN1 MAX3620CETT 3mmX3mm6 TDFN1 MAX3620DETT 3mmX3mm6 TDFN_________________________Features ♦Fully Assembled and Tested♦Additional samples of MAX3620B, MAX3620C, and MAX3620D Devices Included._____________MAX3620 Quick StartThe MAX3620 EV Kit can be configured to evaluate either single-ended or differential signals. For single-ended operation, leave the unused input open. The EV Kit has a calibration trace equal in length to the signal line. If matched cables are used, delay can accurately be determined by measuring the timing between the signal at the calibration strip output and the signal at the output of the MAX3620. The evaluation kit has a 50Ω interface, 50Ω test equipment should be used.To evaluate the MAX3620A:1) Using matched 50ΩSMA cables, connectone output of a differential clock or pulsegenerator, set up for 300MHz operation, toIN1. Connect the other differential output tothe calibration strip (J6).2) Using another set of matched 50ΩSMAcables, connect OUT1 and the output of thecalibration strip (J5) to the inputs of a 50Ωoscilloscope.Note:The timing skew between oscilloscopechannels will affect delay measurements. Besure to perform a skew calibration beforeapplying signals to the oscilloscope.3) Measure the delay from the output of thecalibration strip to OUT1 at the signal mid-points. Because the two polarities of a singledifferential signal are used as two separatesignals, the output of the delay line will be180°out of phase from the output of thecalibration strip. Measure the delay from thecalibration-strip rising edge to the lagging-delay-line falling edge (or from the calibration-strip falling edge to the lagging-delay-linerising edge).If evaluation of MAX3620B, MAX3620C, or MAX3620D is desired, see Table 1 in the MAX3620 datasheet for the recommended operating conditions of each device. When changing between versions, be sure to connect the exposed pad to the EV Kit GND.19-0080; Rev A, 2/05MAX3620 Evaluation Kit 2________________________________________________________________________________E v a l u a t e s : M A X 3620Figure 1.

2.0 Description
The iW3620 is a high performance AC/DC offline LED driver which uses digital control technology to build peak current mode PWM flyback power supplies. The device operates in quasi-resonant mode at heavy load to provide high efficiency along with a number of key built-in protection features while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. The iW3620 removes the need for secondary feedback circuitry while achieving excellent line and load regulation. It also eliminates the need for loop compensation components while maintaining stability over all operating conditions. Pulse-bypulse waveform analysis allows for a loop response that is much faster than traditional solutions, resulting in improved dynamic load response. The built-in current limit function enables optimized transformer design in universal off-line applications over a wide input voltage range.
