Wide input range 4.5V to 21V 36V maximum output voltage with adjustable OVP for smaller output capacitor Drives up to 60 WLEDs in 6 strings Programmable WLED current for up to 30mA per string 1% string-to-string current matching 2.5A integrated power switch Up to 91% efficiency 0.2% to 100% PWM dimming Analog dimming 800KHz switching frequency for small external component Open/short LED protection Short LED protection disable <1uA shut-down current Thermal protection 4mm x 4mm x1mm MLPQ-24 package (WEEE & RoHS compliant)
The SC440 is a high-efficiency multiple string WLED driver with an integrated boost converter. It operates over a wide input range from 4.5V to 21V with a maximum output voltage of 36V and a 2.5A internal power switch. It can drive up to 36V output voltage in 6 strings with current up to 30mA per string. The string-to-string current matching is 1% typical, 3% maximum and the overall efficiency is greater than 90% due to the low current sense voltage and a low-impedance internal power switch. The wide PWM dimming range boasts a ratio of 500: 1. The 800kHz switching frequency enables the user to optimize the external component sizes for high efficiency. When there are fewer LEDs in each string, users can use a lower output voltage protection level which yields an allowable reduction in associated costs, size and voltage ratings of the output capacitor. The SC440 also features a comprehensive open and short circuit LED protection functions. It disables the corresponding strings with LED open or LED short conditions while keeping other strings under normal operation. This feature allows LCD panels to remain viewable even under LED failure, wire disconnect, or shortcircuit conditions. The short LED protection function can be disabled. The internal thermal shutdown protects the IC from overheating at abnormal conditions. The SC440 is available in a common 4mm x 4mm x1mm MLPQ-24 package.

Leave unconnected.Exposed Pad Device GND.3.0 Functional DescriptionThe ZL40205 is an LVPECL clock fan out buffer with six output clock drivers capable of operating at frequencies up to 750MHz.The ZL40205 provides an internal input termination network for DC and AC coupled inputs; optional input biasing for AC coupled inputs is also provided. The ZL40205 can accept DC or AC coupled LVPECL and LVDS input signals, AC coupled CML or HCSL input signals, and single ended signals. A pin compatible device with external termination is also available.The ZL40205 is designed to fan out low-jitter reference clocks for wired or optical communications applications while adding minimal jitter to the clock signal. An internal linear power supply regulator and bulk capacitors minimize additive jitter due to power supply noise. The device operates from 2.5V+/-5% or 3.3V+/-5% supply. Its operation is guaranteed over the industrial temperature range -40°C to +85°C.The device block diagram is shown in Figure 1; its operation is described in the following sections.3.1 Clock InputsThe device has a differential input equipped with two on-chip 50 Ohm termination resistors arranged in series with a center tap. The input can accept many differential and single-ended signals with AC or DC coupling as appropriate. A control pin is available to enable internal biasing for AC coupled inputs. A block diagram of the input stage is in Figure 3.Receiverclk_n 50clk_pVt 50BiasctrlFigure 3 - Simplified Diagram of Input StageThis following figures give the components values and configuration for the various circuits compatible with the input stage and the use of the Vt and ctrl pins in each case.In the following diagrams where the ctrl pin is logically one and the Vt pin is not connected, the Vt pin can be instead connected to VDD with a capacitor. A capacitor can also help in Figure 4 between Vt and VDD. This capacitor will minimize the noise at the point between the two internal termination resistors and improve the overall performance of the device.Figure 4 - Clock Input - LVPECL - DC CoupledFigure 5 - Clock Input - LVPECL - AC CoupledFigure 6 - Clock Input - LVDS - DC CoupledFigure 7 - Clock Input - LVDS - AC CoupledFigure 8 - Clock Input - CML- AC CoupledFigure 9 - Clock Input - HCSL- AC CoupledFigure 10 - Clock Input - AC-coupled Single-EndedFigure 11 - Clock Input - DC-coupled 3.3V CMOS3.2 Clock OutputsLVPECL has a very low output impedance and a differential signal swing between 1V and 1.6 V. A simplified diagram for the output stage is shown in Figure 12.The LVPECL to LVDS output termination is not shown since there is a different device with the same inputs and LVDS outputs.out_pout_nFigure 12 - Simplified Output DriverThe methods to terminate the ZL40205 LVPECL drivers are shown in the following figures.Figure 15 - LVPECL Parallel Thevenin-Equivalent Output TerminationFigure 16 - LVPECL AC Output TerminationFigure 17 - LVPECL AC Output Termination for CML Inputs3.3 Device Additive JitterThe ZL40205 clock fanout buffer is not intended to filter clock jitter. The jitter performance of this type of device is characterized by its additive jitter. Additive jitter is the jitter the device would add to a hypothetical jitter-free clock as it passes through the device. The additive jitter of the ZL40205 is random and as such it is not correlated to the jitter of the input clock signal.The square of the resultant random RMS jitter at the output of the ZL40205 is equal to the sum of the squares of the various random RMS jitter sources including: input clock jitter; additive jitter of the buffer; and additive random jitter due to power supply noise. There may be additional deterministic jitter sources, but they are not shown in Figure 18.Figure 18 - Additive Jitter3.4 Power SupplyThis device operates employing either a 2.5V supply or 3.3V supply.3.4.1 Sensitivity to power supply noisePower supply noise from sources such as switching power supplies and high-power digital components such as FPGAs can induce additive jitter on clock buffer outputs. The ZL40205 is equipped with a low drop out (LDO) regulator and on-chip bulk capacitors to minimize additive jitter due to power supply noise. The on-chip regulation, recommended power supply filtering, and good PCB layout all work together to minimize the additive jitter from power supply noise.3.4.2 Power supply filteringJitter levels may increase when noise is present on the power pins. For optimal jitter performance, the device should be isolated from the power planes connected to its power supply pins as shown in Figure 19. •10 µF capacitors should be size 0603 or size 0805 X5R or X7R ceramic, 6.3 V minimum rating •0.1 µF capacitors should be size 0402 X5R ceramic, 6.3 V minimum rating •Capacitors should be placed next to the connected device power pins •A 0.15 Ohm resistor is recommended3.4.3 PCB layout considerationsThe power nets in Figure 19 can be implemented either as a plane island or routed power topology without changing the overall jitter performance of the device.ZL402051891922320.1 µF 0.1 µFvdd_core10 µF 0.1 µF0.15 Ωvdd0.1 µF 10 µFFigure 19 - Decoupling Connections for Power PinsAbsolute Maximum Ratings*Parameter Sym.Min.Max.Units 1Supply voltage V DD_R-0.5 4.6V 2Voltage on any digital pin V PIN-0.5VDD V 4LVPECL output current I out30mA 5Soldering temperature T260 °C 6Storage temperature T ST-55125 °C 7Junction temperature T j125 °C 8Voltage on input pin V input VDD V 9Input capacitance each pin C p500fF 4.0 AC and DC Electrical Characteristics* Exceeding these values may cause permanent damage.

Series SCT电流变压器商品说明说明书

The Series SCT Current Transformers continuously measure the current consumption of pumps, fans, boilers, solar panels and chillers for use in energy monitoring. Current or voltage outputs can be scaled using a slider switch to select between three factory set ranges. Split core configuration allows the current transformer to be installed on new and existing installations. Snap-on mounting bracket allows for quick installation of replacement transformers. An optional 10 A command relay can snap onto the current switch which eliminates the need to mount an additional relay.INSTALLATIONMOUNTING1. Detach the plastic mounting bracket from the current switch housing.2. Using the two included screws, attach the mounting bracket to the rear of the electrical panel or enclosure.3. Re-attach the current switch housing to the plastic mounting bracket.WIRING1. Disconnect the power to the conductor cable from the power source.2. Open the core using the release tab. Snap the core closed around the power conductor cable. Make sure that the core release tab is locked in its original position.3. Wire the Series SCT as shown in the below wiring diagrams.4. Reconnect the power conductor cable.SPECIFICATIONSAmperage Range: 30/60/120 A or 20/100/150 A (depending on model).Continuous Operating Current: 120 A or 150 A (depending on model).Output: 4 to 20 mA, 0 to 5 VDC, 0 to 10 VDC (depending on model).Optional relay N.O. SPST; 10 A @ 260 VAC, 5 A @ 30 VDC.Power Requirements:Self-powered or 24 VDC (depending on model).Accuracy:±2% from 10 to 100% of selected range.Temperature Limits: 5 to 140°F (-15 to 60°C).Humidity Limits: 0 to 95% non-condensing.Response Time: 2 seconds.Isolation Voltage: 600 VAC RMS.Frequency: 50/60 Hz.Enclosure Rating: UL, V-O flammability rated, type 66 nylon. Agency Approvals: CE, RoHS, UL.Disconnect the power supply before making electricalconnections. Contact with components carrying hazardousvoltage can cause electrical shock and may result in severe personal injury or death.The Series SCT Current Transformers are intended to provide an input to equipment under normal operating conditions.Additional precautions must be designed into the control system where failure or malfunction of the current transformer could lead to personal injury or property damage to the controlled equipment or other property. Incorporate and maintain other devices such as supervisory, alarm systems, safety or limit controls intended to warn of or protect against failure or malfunction of the SCT.Figure 1: Wiring Diagram for Current Output Models.Figure 2: Wiring Diagram for 0 to 5 and 0 to 10 VDC Models. SCALING OUTPUT RANGESet the amperage range at a level appropriate for the load. Use the slide switch onFigure 3: Selection of Output Scaling. INCREASING/DECREASING MEASURED CURRENTIf the measured current is too low to be detected or is higher than the maximum current rating of the SCT, use the following methods to increase or decrease current.If measured current is too low to be detected:Wrap the conductor (wire) through the sensing hole and around the SCT body to produce multiple turns to increase the measured current. Use the below equation to determine how many wraps are necessary:: number of turns: actual current: measured currentFigure 4: Wind the conductor through the core to increase current e the following formula to determine the new maximum current:: number of turns: SCT current rating: new maximum currentFor example, Model SCT10-100 with 4 turns: , new maximum current.If measured current is above ratings of the switch:Use a 5 A Current Transformer (CT) to reduce the current passing through the SCT.Run the current transformer secondary wire through the sensing hole. Terminate the 2 secondary wires of the 5 A current transformer to each other, and then install the 5 A current transformer on the monitored conductor.Figure 5: Use a 5 A current transformer’s secondaryloop to reduce amount of current sensed.MAINTENANCE/REPAIRUpon final installation of the Series SCT, no routine maintenance isrequired. The Series SCT is not field serviceable and should be returned if repair is needed. Field repair should not be attempted and may void warranty.WARRANTY/RETURNRefer to “Terms and Conditions of Sales” in our catalog and on our website. Contact customer service to receive a Return Goods Authorization number before shipping the product back for repair. Be sure to include a brief description of the problem plus any additional application notes.SCT20-10320/100/150 A0 to 10 VDC Self-powered150 A Icr N=Inm NInmIcrN x Ia=Im N IaImFailure to de-rate the current capacity could result in damage tothe Series SCT when using multiple turns to increase the measured current.120A4=30.0 A©Copyright 2018 Dwyer Instruments, Inc.FR# 443900-00 Rev. 1。

DESIGN DETAILTD_SX440 AVR_03.05_03_GBSX440 AUTOMATIC VOLTAGEREGULATOR (AVR)SPECIFICATION, INSTALLATION AND ADJUSTMENTSGeneral descriptionTechnical specificationSX440 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator (AVR) and forms part of the excitation system for a brush-less generator.In addition to regulating the generator voltage, the AVR circuitry includes under-speed and sensing loss protection features. Excitation power is derived directly from the generator terminals.Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR.The AVR is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/- 1.0%.In addition to being powered from the main stator, the AVR also derives a sample voltage from the output windings for voltage control purposes. In response to this sample voltage, the AVR controls the power fed to the exciter field, and hence the main field, to maintain the machine output voltage within the specified limits, compensating for load, speed, temperature and power factor of the generator.A frequency measuring circuit continually monitors thegenerator output and provides output under-speed protection of the excitation system, by reducing the output voltage proportionally with speed below a pre-settable threshold. A manual adjustment is provided for factory setting of the under frequency roll off point, (UFRO). This can easily be changed to 50 or 60 Hz in the field by push-on link selection.Provision is made for the connection of a remote voltage trimmer, allowing the user fine control of the generator's output.An analogue input is provided allowing connection to a Newage Power Factor controller or other external devices with compatible output.The AVR has the facility for droop CT connection, to allow parallel running with other similarly equipped generators.INPUTVoltage 190-264V ac Frequency 50-60 Hz nominal Phase 1 Wire 2 OUTPUT Voltage max 90V dc at 207V ac input Current continuous 4A dc Intermittent 6A for 10 secs Resistance 15 ohms minimum REGULATION +/- 1% (see note 1)THERMAL DRIFT 0.04% per deg.

Non condensing.DESIGN DETAILTD_SX440 AVR_03.06_03_GBThe main functions of the AVR are:Potential Divider and Rectifier takes a proportion of the generator output voltage and attenuates it. The potential divider is adjustable by the AVR Volts potentiometer and external hand trimmer (when fitted). The output from the droop CT is also added to this signal. An isolating transformer is included allowing connection to various winding configurations. A rectifier converts the a.c. input signal into d.c. for further processing.The Sensing Loss Detector is an electronic changeover switch, which normally connects the Amplifier (Amp) to the Voltage Sensing input and automatically changes over to the Power input when the normal sensing voltage is lost.The DC Mixer adds the Analogue input signal the Sensing signal.The Amplifier (Amp) compares the sensing voltage to the Reference Voltage and amplifies the difference (error) to provide a controlling signal for the power devices. The Ramp Generator and Level Detector and Driver infinitely control the conduction period of the Power Control Devices and hence provides the excitation system with the required power to maintain the generator voltage within specified limits.The Stability Circuit provides adjustable negative ac feedback to ensure good steady state and transient performance of the control system.The Low Hz Detector measures the period of each electrical cycle and causes the reference voltage to be reduced approximately linearly with speed below a presettable threshold. A Light Emitting Diode gives indication of underspeed running.The Synchronising circuit is used to keep the Ramp Generator and Low Hz Detector locked to the generator waveform period.The Low Pass Filter prevents distorted waveforms affecting the operation of the AVR control circiutPower Control Devices vary the amount of exciter field current in response to the error signal produced by the Amplifier.Suppression components are included to prevent sub cycle voltage spikes damaging the AVR components and also to reduce the amount of conducted noise on the generator terminals..The Power Supply provides the required voltages for the AVR circuitry.Hand TrimmerAnalogue InputDroopFITTING AND OPERATINGTD_SX440 AVR _03.06_03_GBSUMMARY OF AVR CONTROLSCONTROL FUNCTIONDIRECTIONVOLTS TO ADJUST GENERATOR OUTPUT VOLTAGE CLOCKWISE INCREASES OUTPUT VOLTAGE STABILITY TO PREVENT VOLTAGE HUNTING CLOCKWISE INCREASE THE DAMPING EFFECT UFRO TO SET THE UFRO KNEE POINTCLOCKWISE REDUCES THE KNEE POINT FREQUENCYDROOP TO SET THE GENERATOR DROOP TO 5% AT 0PF CLOCKWISE INCREASES THE DROOPVTRIMTO OPTIMISE ANALOGUE INPUT SENSITIVITYCLOCKWISE INCREASES THE GAIN OR SENSITIVITYADJUSTMENT OF AVR CONTROLSVOLTAGE ADJUSTMENTThe generator output voltage is set at the factory, but can be altered by careful adjustment of the VOLTS control on the AVR board, or by the external hand trimmer if fitted. Terminals 1 and 2 on the AVR will be fitted with a shorting link if no hand trimmer is required.CAUTION Do not increase the voltage above the rated generator voltage. If in doubt, refer to the rating plate mounted on the generator case.CAUTION Do not ground any of the hand trimmer terminals as these could be above earth potential. Failure to observe this could cause equipment damage.If a replacement AVR has been fitted or re-setting of the VOLTS adjustment is required, proceed as follows:CAUTION1. Before running generator, turn the VOLTS control fully anti-clockwise.2. Turn remote volts trimmer (if fitted) to midway position.3. Turn STABILITY control to midway position.4. Connect a suitable voltmeter (0-300V ac) across line to neutral of the generator.5. Start generator set, and run on no load at nominal frequency e.g. 50-53Hz or 60-63Hz.6. If the red Light Emitting Diode (LED) is illuminated, refer to the Under Frequency Roll Off (UFRO) adjustment.7. Carefully turn VOLTS control clockwise until rated voltage is reached.8. If instability is present at rated voltage, refer to stability adjustment, then re-adjust voltage if necessary.9. Voltage adjustment is now completed.FITTING AND OPERATINGTD_SX440 AVR_03.06_04_GBBarnack Road • Stamford • Lincolnshire • PE9 2NB Tel: 00 44 (0)1780 484000 • Fax: 00 44 (0)1780 484100© 2006 Cummins Generator Technologies Limited.Printed in England.STABILITY ADJUSTMENTThe AVR includes a stability or damping circuit to provide good steady state and transient performance of the generator.The correct setting can be found by running the generator at no load and slowly turning the stability control anti-clockwise until the generator voltage starts to become unstable.The optimum or critically damped position is slightly clockwise from this point (i.e. where the machine volts are stable but close to the unstable region).OPTIMUM RESPONSE SELECTIONThe stability selection ‘jumper’ should be correctly linked, A-B, B-C or A-C at the bottom of the board for the frame size of the generator, (see drawing).UNDER FREQUENCY ROLL OFF (UFRO) ADJUSTMENTThe AVR incorporates an underspeed protection circuit which gives a volts/Hz characteristic when the generator speed falls below a presettable threshold known as the "knee" point.The red Light Emitting Diode (LED) gives indication that the UFRO circuit is operating.The UFRO adjustment is preset and sealed and only requires the selection of 50 / 60Hz using the jumper link.For optimum setting, the LED should illuminate as the frequency falls just below nominal, i.e. 47Hz on a 50Hz system or 57Hz on a 60Hz system.DROOP ADJUSTMENTGenerators intended for parallel operation are fitted with a quadrature droop C.T. which provides a power factor dependent signal for the AVR. The C.T. is connected to S1, S2 on the AVR.The DROOP adjustment is normally preset in the works to give 5% voltage droop at full load zero power factor.Clockwise increases the amount of C.T. signal injected into the AVR and increases the droop with lagging power factor (cos Ø). With the control fully anti-clockwise there is no droop.TRIM ADJUSTMENTAn analogue input (A1 A2) is provided to connect to the Newage Power Factor Controller or other devices. It is designed to accept dc signals up to +/- 5 volts.CAUTION Any devices connected to this input must be fully floating and galvanically isolated from ground, with an insulation capability of 500 Vac. Failure to observe this could result in equipment damage.The dc signal applied to this input adds to the AVR sensing circuit. A1 is connected to the AVR 0 volts. Positive on A2 increases excitation. Negative on A2 decreases excitation.The TRIM control allows the user to adjust the sensitivity of the input. With TRIM fully anti-clockwise the externally applied signal has no effect. Clockwise it has maximum effect.Normal setting is fully clockwise when used with a Newage Power Factor Controller.。

AM -Receiver CircuitPackageTechnical DataTCA 440 / TEdition 12/95DescriptionThis is an efficient bipolar monolithic circuit to apply in battery -powered or mains -operated radio receivers up to 30 MHz. It contains controlled RF stage, mixer, separated oscillator and regulated multistage IF amplifier.Features• symmetrical structured circuitry • controlled RF prestage• multiplicative balanced mixer, separated oscillator • very well implemented large -signal characteristic begins already from 4.5 V supply voltage • terminals for indicating instrument• controlled IF amplifier implementing 60 dB control range• external demodulator (diode)• wide range of supply voltage between 4.5 and 15 VPin configuration1RF prestage, input 19input IF control amplifier2RF prestage, input 210indicator output IF control amplifier 3RF control amplifier input11IF blocking4oscillator circuit pin 112input lF amplifier5oscillator circuit pin 213IF blocking6oscillator circuit pin 314supply voltage7IF output15mixer output 18ground16mixer output 2Block diagramFunctional descriptionIt contains several function units, which enable designing and assembling of efficient AM tuners. Caused by internal voltage stabilization characteristics are rather independent from supply voltage.The RF input signal reaches via a controllable and overdriving proof preselector stage a balanced mixer. By means of a RF -signal generated by a separated oscillator the input signal is transported into IF. Multiplicative mixing causes only few harmonic content. Gain control is carried out by means of two separated feedback control loops for preselector stage and IF amplifier. By these a loop bandwidth of approximately 100 dB is obtained. The control voltage of the IF -amplifier can be used to drive a moving -coil instrument (field strength indicator). The IF amplifier consists of 4 amplifier stages, the first, second and third can be controlled. The bandwidth of the IF amplifier is approximately 2 MHz and on that account sufficient for usual IF frequencies in the AM range of approximately 460 kHz.The symmetrical arrangement of the entire circuitry guarantees well oscillating. The bridge of the mixer avoids direct breakdown.Absolute maximum ratingsmin max unitSupply voltage V CC 4.515.0VJunction temperature T j150°CAmbient operating temperature T a-1580°CStorage temperature T s-40125°CTotal thermal resistance R thja120K/W Recommended operational conditionsmin max unitSupply voltage V CC 4.515VAmbient operating temperature T a-1070°CCharacteristicsrefer to application examples, f i= 1 MHz, f osc= 1.455 kHz, f lF= 455 kHz, V CC= 9 V, f m= 1 kHz, m = 0.8, voltages refer to ground, T a= 20 to 25 °C, unless specified otherwisemin typ max unit Current and voltage supply(no RF signal)Supply voltage V14-8 4.5915V Current consumptionV14-8= 4.5 V I147mAV14-8= 9 V I1410.516mAV14-8= 15 V I1412mA Entire receiverRF level variationwith ∆V NF= 6 dB∆V RF65dBwith ∆V NF= 10 dB∆V RF80dBNF output voltages(symmetrically measured at 1-2)V iHF= 20 µV, m = 0.8V NF(rms)60140mVV iHF= 1 mV, m = 0.8V NF(rms)260mVV iHF= 500 mV, m = 0.8V NF(rms)100350560mVV iHF= 20 µV, m = 0.3V NF(rms)50mVV iHF= 1 mV, m = 0.3V NF(rms)100mVV iHF= 500 mV, m = 0.3V NF(rms)130mVRF input sensitivitymeasured at 60 Ω, m = 0.3,R G= 540 Ωsignal-to-noise ratioS + N/N = 6 dB V iRF1µVS + N/N = 26 dB V iRF7µVS + N/N = 58 dB V iRF1mVMaximum RF input voltage V iHF 1.5V (THD = 10 %)Total harmonic distortionV HF= 500 mV THD 4.510%V HF= 30 mV THD 2.88%RF partInput frequency range f iHF050MHz Output frequencyf|F= f osc-f iHF f IF455kHz Control range∆G V38dB412/95min typ max unitIF suppression a lF20dB between 1 -2 and 15RF input impedanceunbalanced couplingV iHFmax Z i 2 II 5kΩIIpF V iHFmin Z i 2.2 II 1.5kΩIIpF balanced couplingV iHFmax Z i 4.5kΩV iHFmin Z i 4.5 II 1.5kΩIIpFMixer output impedance(pin 15 or 16)Z o250 II 4.5kΩIIpF Steepness S HF28mS IF partInput frequency range f ilF02MHzControl range∆G V62dB f ilF= 455 kHz, ∆V NF= 10 dBStart of control V ctrlF140µV (∆V iIF/ ∆V NF= 10 dB / 3 dB)maximum IF input voltage V ilFmax200mV (THD NF= 10 %)NF output voltageapplied to 60 ΩV ZF= 30 µV V NF(rms)50mV V ZF= 3 mV V NF(rms)200mV V ZF= 3 mV; m = 0.3V NF(rms)70mVIF input impedance(unbanlanced coupling)Z ilF 3 II 3kΩllpFIF output impedance Z O200 II 8kΩIIpF (pin 7)Indication instrumentRecommended indication instruments: 500 µA (R i= 800 Ω)300 µA (R i= 1.5 kΩ)For indication a voltage source of 600 m V(EMF)and an internal source impedance of 400 Ωis available.Dependences612/95812/95Application examples1012/95元器件交易网Application hintsThe PCB is to arrange such that there are maximum ground lines (ground area) voltage supply has to be blocked to ground by a capacitor of 10...100 nF in order to avoid distortions. Blocking should be as close as possible to the circuit.The RF circuit has to layout such that 150 mV(rms)oscillator voltage are applied to pin 5. Symmetrically applying an external oscillator is possible to pin 4 or pin 5. The unused input must be connected to ground via capacitor and in the same time be connected to supply voltage at pin 6.It is recommendable to profide off earth connections 1 and 3, because in this way common -mode interferences more effectively can be suppessed. Single -sided capacitive control of pin 1 and 2 is possible, the unused input must be connected to ground via capacitor.Mixer outputs 15 and 16 can be used equivalently.Load resistances of the mixer (IF selection) at pin 15 respectively pin 16 should run to approximately 7 kΩ.To avoid saturation of the multiplier the maximum peak voltage occuring during operation should not exceed the level (V CC-3 V) IF response to voltage from pin 15 respectively pin 16 to pin 12 should be approximately -18 dB that the control characteristics of IF -and RF -part optimally be matched.Peak voltage at pin 7 occuring during operation should not exceed 2 V that the IF output does not go intosaturation.All the RF bypass capacitors should amount to 100 nF. Sufficient decoupling of wavemagnet and oscillator coil is to be taken into consideration.All components and parts must be carefully proportioned in order to obtain optimum wise characteristics.Wavemagnets applied should so much mass as possible. The transformation ratio of the input circuitry should run to 10...12.In order to improve RF response characteristic a RF preselector can be additionally preceded or the wavemagnet can be tighty coupled by means of an emitter follower impedance transformer.Improvement of signal -to -noise ratio at average input voltages can be obtained by delayed control of the RF part. Control should be start at approximately 1...2 mV.Reprinting is generally permitted, indicating the source.

I OV IN. I INx100%Efficiency Design ConsiderationsInput FilteringThe power module should be connected to a lowac-impedance source. Highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 13, a 33μF electrolytic capacitor (ESR<0.1Ω at 100kHz), mounted close to the power module helps ensure the stability of the unit. Consult the factory for further application guidelines.Safety ConsiderationsFor safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL 60950-1-3, CSA C22.2 No. 60950-00, and VDE 0805:2001-12 (IEC60950-1).If the input source is non-SELV (ELV or a hazardous voltage greater than 60 Vdc and less than or equal to 75Vdc), for the module’s output to be considered as meeting the requirements for safety extra-low voltage (SELV), all of the following must be true:The input source is to be provided with reinforced insulation from any other hazardous voltages,including the ac mains.One V IN pin and one V OUT pin are to be grounded, or both the input and output pins are to be keptfloating.The input pins of the module are not operator accessible.Another SELV reliability test is conducted on the whole system (combination of supply source andsubject module), as required by the safetyagencies, to verify that under a single fault,hazardous voltages do not appear at the module’s output.Note:Do not ground either of the input pins of the module without grounding one of the outputpins. This may allow a non-SELV voltage toappear between the output pins and ground. The power module has extra-low voltage (ELV) outputs when all inputs are ELV.All flammable materials used in the manufacturing of these modules are rated 94V-0, or tested to theUL60950 A.2 for reduced thickness.For input voltages exceeding –60 Vdc but less than or equal to –75 Vdc, these converters have been evaluated to the applicable requirements of BASIC INSULATION between secondary DC MAINS DISTRIBUTION input (classified as TNV-2 in Europe) and unearthed SELV outputs (-B option only).The input to these units is to be provided with a maximum 5 A time-delay fuse in the ungrounded lead.Feature DescriptionRemote On/OffTwo remote on/off options are available. Positive logic turns the module on during a logic high voltage on the ON/OFF pin, and off during a logic low. Negative logic remote On/Off, device code suffix “1”, turns the module off during a logic high and on during a logic low.Figure 16. Remote On/Off Implementation.To turn the power module on and off, the user must supply a switch (open collector or equivalent) to control the voltage (V on/off) between the ON/OFF terminal and the V IN(-) terminal (see Figure 16). Logic low is0V ≤ V on/off≤ 1.2V. The maximum I on/off during a logic low is 1mA, the switch should be maintain a logic low level whilst sinking this current.The typical open circuit V on/off generated by the module is 3.4V. The I ON/OFF leakage current, through the switch, is required to be less than 10uA otherwise the unit will reach the threshold at which it switches.If not using the remote on/off feature:For positive logic, leave the ON/OFF pin open.For negative logic, short the ON/OFF pin to V IN(-). Remote SenseRemote sense minimizes the effects of distribution losses by regulating the voltage at the remote-sense connections (See Figure 17). The voltage between the remote-sense pins and the output terminals must not exceed the output voltage sense range given in the Feature Specifications table:[V O(+) – V O(–)] – [SENSE(+) – SENSE(–)] ≤ 10% V O,Set Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim.The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power (Maximum rated power = V o,set x I o,max).Figure 17. Circuit Configuration for remotesense .Input Under-Voltage LockoutAt input voltages below the input under-voltage lockout limit, the module operation is disabled. The module will only begin to operate once the input voltage is raised above the undervoltage lockout turn-on threshold,V uv/on.Once operating, the module will continue to operate until the input voltage is taken below the undervoltage turn-off threshold, V uv/off.Over-Temperature ProtectionTo provide protection under certain fault conditions, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the thermal reference test pointRT1 (Figure 19), exceeds 110o C (typical), but the thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. The module will automatically restart upon cool-down to a safe temperature.Output Over-Voltage ProtectionThe output over-voltage protection scheme of the modules has an independent over-voltage loop to prevent single point of failure. This protection feature latches-off the module in the event of over-voltage across the output. Recycling the input voltage or momentarily switching-off the module via the remote on/off pin resets the latch.The independent over-voltage loop has a relatively slow response time. There are no precautions necessary to meet the output over-voltage protection limits for externally caused over-voltage conditions, such as excessive remote sense or output trim adjustments. However, special precautions are necessary to insure the over-voltage limits are met when the over-voltage is caused by internal module control loop failure. Either a minimum of 660 µF external output capacitance is required, or an externalFeature Descriptions (continued)OVP pull-down circuit is required. The OVP pull-down circuit will also provide significantly lower peak output over-voltages for applications that are particularly sensitive to over-voltage stress. Please contact your local Lineage Power sales representative for further information on the external OVP pull-down circuit.Over-Current ProtectionTo provide protection in a fault (output overload)condition, the unit is equipped with internalcurrent-limiting circuitry and can endure current limiting continuously. At the point of current-limit inception, the unit enters hiccup mode. The unit will remain in the hiccup mode as long as the overcurrentcondition exists; it operates normally, once the output current is brought back into its specified range. The average output current during hiccup is < 1A.Output Voltage ProgrammingTrimming allows the output voltage set point to be increased or decreased. This is accomplished byconnecting an external resistor between the TRIM pin and either the V O (+) pin or the V O (-) pin.LOADFigure 18. Circuit Configuration to Trim Output Voltage.Connecting an external resistor (R trim-down ) between the TRIM pin and the V O (-) (or Sense(-)) pin decreases the output voltage set point.

This limit includes any increase in voltage due to remote-sense compensation and output voltage set-point adjustment trim.Although the output voltage can be increased by both the remote sense and by the trim, the maximumincrease for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim. The amount of powerdelivered by the module is defined as the voltage at the output terminals multiplied by the output current.

Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power (Maximum rated power = V o,set x I o,max ).EMC ConsiderationsThe KW006/010 power module is designed to meet EN55022 Class B Conducted emissions with a simple filter, as shown in Figure 19. Test results are shown in Figure 20. Further improvement to the emissions at the fundamental can be achieved by increasing the value of C3 and C4. Please contact your Lineage Power sales representative, if you need further information.Figure 19. EMC Filter.Thermal ConsiderationsThe power modules operate in a variety of thermalenvironments; however, sufficient cooling should beprovided to help ensure reliable operation.Considerations include ambient temperature, airflow,module power dissipation, and the need for increasedreliability. A reduction in the operating temperature ofthe module will result in an increase in reliability. Thethermal data presented in this data sheet is based onphysical measurements taken in a wind tunnel.

SC1485ITSTRT资料

SC1485
The SC1485 is a dual output constant-on synchronous buck PWM controller intended for use in notebook computers and other battery operated portable devices. Features include high efficiency and a fast dynamic response with no minimum on time. The excellent transient response means that SC1485 based solutions will require less output capacitance than competing fixed frequency converters. The switching frequency is constant until a step in load or line voltage occurs at which time the pulse density and frequency will increase or decrease to counter the change in output or input voltage. After the transient event, the controller frequency will return to steady state operation. At light loads, Power-Save Mode enables the SC1485 to skip PWM pulses for better efficiency. Each output voltage can be independently adjusted from 0.5V to VCCA. Two frequency setting resistors set the on-time for each buck controller. The frequency can thus be tailored to minimize crosstalk. The integrated gate drivers feature adaptive shoot-through protection and soft switching. Additional features include cycle-by-cycle current limit, digital soft-start, over-voltage and undervoltage protection, and a PGOOD output for each controller.

In addition to the requirements of EMC compatibility, the computing devices are required to tolerate ESD events and remain operational without user intervention.The KBMF implements a low pass filter to limit EMI levels and provide ESD protection which exceeds IEC 61000-4-2 level 4 standard. The device also implements the pull up resistors needed to bias the data and clock lines. The package is the SOT23-6L which is ideal for situations where board space is at a premium.BENEFITS■EMI / RFI noise suppression■ESD protection exceeding IEC61000-4-2 level 4■High flexibility in the design of high density boardsIPAD™Table 1: Order CodePart NumberMarking KBMF01SC6KM1TM: IPAD is a trademark of STMicroelectronics.COMPLIES WITH THE FOLLOWING ESD STANDARDS:IEC 61000-4-2 (R = 330Ω C = 150pF)Level 4±15 kV (air discharge)±8 kV (contact discharge)MIL STD 883C, Method 3015-6Class 3 C = 100pF R = 1500Ω3 positive strikes and3 negative strikes (F = 1 Hz)KBMF2/8Table 2: Absolute Maximum Ratings (T amb = 25°C)Table 3: Electrical Characteristics (T amb = 25°C)TECHNICAL INFORMATION 1.

ESD PROTECTIONThe KBMFxxSC6 is particularly optimized to perform ESD protection. ESD protection is based on the use of device which clamps at:V output = V BR + R d .I PPThis protection function is splitted in 2 stages. As shown in figure 4, the ESD strikes are clamped by the first stage S1 and then its remaining overvoltage is applied to the second stage through the resistor R.Such a configuration makes the output voltage very low at the V output level.To have a good approximation of the remaining voltages at both V input and V output stages, we give the typical dynamical resistance value Rd. By taking into account these following hypothesis : R t >R d , R g >R d and R load >R d , it gives these formulas:The results of the calculation done for V PP =8kV, R g =330Ω (IEC 61000-4-2 standard), V BR =7V (typ.) and R d = 1Ω (typ.) give:V input = 31.2 V V output = 7.8 VThis confirms the very low remaining voltage across the device to be protected. It is also important to note that in this approximation the parasitic inductance effect was not taken into account. This could be few tenths of volts during few ns at the input side. This parasitic effect is not present at the output side due the low current involved after the resistance R S .The measurements done here after show very clearly (figure 6) the high efficiency of the ESD protection :- no influence of the parasitic inductances on output stage- V output clamping voltage very close to V BR (positive strike) and -V F (negative strike)V input =R g V BR R d V g⋅+⋅R g -----------------------------------------------------V output =R s V BR R d V input⋅+⋅R t----------------------------------------------------------------KBMFFigure 6: Remaining voltage at both stages S1 (V input) and S2 (V output) during ESD surgePositive surge Negative surgePlease note that the KBMF01SC6 is not only acting for positive ESD surges but also for negative ones. For these kind of disturbances it clamps close to ground voltage as shown in the Negative Surge figure.3. LATCH-UP PHENOMENAThe early ageing and destruction of IC’s is often due to latch-up phenomena which is mainly induced by dV/dt. Thanks to its structure, the KBMF01SC6 provides a high immunity to latch-up phenomena by smoothing very fast edges.4/8KBMF5/84. CROSSTALK BEHAVIOR The crosstalk phenomena is due to the coupling between 2 lines. The coupling factor ( β12 or β21 )increases when the gap across lines decreases, this is the reason why we provide crosstalk measurements for monolithic device to guarantee negligeable crosstalk between the lines. In the example above the expected signal on load R L2 is α2V G2, in fact the real voltage at this point has got an extra value β21V G1. This part of the V G1 signal represents the effect of the crosstalk phenomenon of the line 1 on the line 2. This phenomenon has to be taken into account when the drivers impose fast digital data or high frequency analog signals in the disturbing line. The perturbed line will be more affected if it works with low voltage signal or high load impedance (few k Ω).Figure 8 gives the measurement circuit for the analog crosstalk application. In figure 9, the curve shows the effect of the Data line on the CLK line. In usual frequency range of analog signals (up to 100MHz) the effect on disturbed line is less than -37dB.Figure 7: Crosstalk phenomenaFigure 8: Analog Crosstalk measurementsFigure 9:Typical Analog Crosstalk meas-KBMF6/8Figure 10 shows the measurement circuit used to quantify the crosstalk effect in a classical digital appli-cation.Figure 11 shows that in such a condition signal from 0 to 5V and rise time of few ns, the impact on the other line is less than 50mV peak to peak (below the logic high threshold voltage).
