LM3485LED Demo BoardIntroductionThe LM3485LED driver board is a buck regulator derived controlled current source designed to drive high power,high brightness LEDs (HBLEDs)such as the Luxeon ™Emitter at dissipations of 1W to 5W.The board can accept an input voltage ranging from 5V to 30V and can control the output current delivered to series and/or parallel arrays of HBLEDs as long as the forward voltage of all LEDs in series is less than (0.9x VIN).The accuracy of the output current is ±10%.Setting the LED CurrentThe forward current IF delivered to the LED array is set by the program jumper,P2.If no jumper is installed,the LM3485will default to the lowest current setting,350mA.Installing a jumper as shown in Figure 1will change the current regulation point to 700mA,100mA,or 1400mA,respectively.PWM DimmingDiode D2provides an input for a pulse width modulation signal for dimming of the LED array.In order to fully enable and disable the LM3485the PWM signal should have a maximum logic low level of 1.0V,a minimum logic high level of 2.0V,and minimum low and high periods of 40µs.For example,at 100Hz,the minimum and maximum duty cycles to which the LM3485can respond are 0.4%and 99.6%,respectively.At 1kHz,the minimum and maximum duty cycles are 4%and 96%,respectively.The logic of the PWM is inverted,hence the LM3485will deliver regulated output current when the voltage at the PWM IN terminal is low,and the current output is disabled when the voltage at the PWM IN terminal is high.Connecting a constant logic high to the PWM IN will disable the output.Output Open CircuitWith PWM IN floating or connected to logic low,the LM3485will begin to operate as soon as is has an input of at least 5V.In the case that the input is powered but no LED array is connected the output voltage will rise to equal the input voltage.The output of the circuit is rated to 30V and will not suffer damage,however care should be taken not to connect an LED array if the output voltage is higher than the target forward voltage of the LED array in steady state.20157701FIGURE 1.Current Settings of P2National Semiconductor Application Note 1392Chris Richardson June

Supertex inc.HV9961DB190-265VAC50/60Hz0 -1.5V for LD function or leave openGeneral DescriptionThe HV9961 demoboard is a high-brightness LED driver employing the patent-pending average-mode constant current control scheme by Supertex Inc. The power conversion stage of the HV9961DB1 consists of a diode bridge rectifier followed by a buck converter operating with fixed off-time of 20µs.The HV9961DB1 LED driver features tight regulation of the LED current within a few milliamps over the entire rangeof the input AC line and the output LED string voltage. The LED current accuracy is almost insensitive to the passive component tolerances, such as the output filter inductance or the timing resistor. The accuracy of the LED current is mainly determined by the internal 275mV ± 3% referencevoltage of the HV9961 control IC and by the external current sense resistor tolerance. The output current can be adjusted down to 60mA using an on-board potentiometer. However, the accurate current control is only achieved with continuous conduction of the filter inductor, i.e. when the LED current is greater than the inductor ripple current amplitude. (Note, that the linear dimming input of the HV9961 disables switching, when its voltage falls below a 200V threshold. Expect the LED driver to shut off when the LED current falls below 50 ~ 55mA.)PWM dimming can be achieved by applying a pulse-width-modulated square wave signal between the PWMD andGND pins.The HV9961DB1 features protection from an output short circuit condition. Open LED protection is inherent, since the output filter capacitor can accept the full rated rectified AC line voltage. Please, note that the demoboard is not CISPR15 compliant. An additional input EMI filter circuit is required to make the board meet conducted electro-magnetic emission limits. Also, note that:NO SAFETY ISOLATION OF THE LED LOADFROM THE AC MAINS VOLTAGE IS PROVIDED!21-Watt Universal AC LED Driver Demoboard with Accurate Average-Mode Constant Current ControlConnection DiagramWARNINGDo not connect earth-grounded test instruments. Doing so will short the AC line, resulting in damage to the instrument and/or the HV9961DB1. Use floating high voltage differential probes or isolate the demoboard by usingan isolating transformer.WARNINGNo galvanic isolation.Dangerous voltages are present when connected to the AC line.1. Connect the input AC voltage between the AC INterminals as shown in the connection diagram.2. Connect the LED string between LED+ (anode ofLED string) and LED- (cathode of LED string).3. Connect the PWMD terminal to the VDD terminalusing the jumper provided to enable the LED driver.4. The current level can be adjusted by applying 0 -1.5V between LD and GND. Leave LD floating to use the internal current setting.ConnectionsPWM DimmingThe HV9961DB1 is capable of being PWM dimmed by ap-plying a square wave TTL compatible signal between PWMD and GND terminals. However, since there is no galvanic iso-lation on the board, care must be taken to prevent damage to the PWM dimming source and/or the HV9961DB1. One simple way is to isolate the LED driver from the AC line using an isolation transformer. Another approach is to use an opto-isolator to drive the PWMD pin as shown in the figure below.5.0Vsquarewavesignal(<1.0kHz)PWMDVDD(e.g. LTV-814 from Lite-On)L E D C u r r e n t (A )AC Line Voltage (VAC)AC Line Voltage (VAC)0.3620.3600.3580.3560.3540.3520.3500.3480.346L E D C u r r e n t (A )PWM Dimming Response Short Circuit CurrentI LEDPWMDV IN = 240VAC0.3400.3450.3550.3600.3650.370Typical CharacteristicsSchematicJ3B J3C Silk ScreenSupertex inc. does not recommend the use of its products in life support applications, and will not knowingly sell them for use in such applications unless it receives an adequate “product liability indemnification insurance agreement.” Supertex inc. does not assume responsibility for use of devices described, and limits its liability to the replacement of the devices determined defective due to workmanship.
