Supertex inc.HV9930DB1General DescriptionThe HV9930DB1 is an LED driver demoboard capable of driving up to 7 1-watt LEDs in series from an automotive input of 9 - 16VDC. The demoboard uses Supertex’s HV9930 in a boost-buck topology. The converter operates at frequencies in excess of 300kHz and has excellent output current regulation over the input voltage range. It can also withstand transients up to 42V and operate down to 6V input. The converter is also protected against open LED and output short circuit conditions. Protection against reverse polarity up to 20V is also included.Board Layout and Connection DiagramHigh Bright LED Driver IC DemoboardMeeting Automotive RequirementsConnections:Input - The input is connected between the terminals of connector J1 as shown in the Connection Diagram.Output - The output is connected between the terminals of connector J2 as shown.Enable/PWM Dimming:To just enable the board, short pins 1 and 2 of connector J3 as shown. For PWM dimming, connect the external push-pullsquare wave source between terminals 1 and 3 of connectorJ3 as shown by the dotted lines.Note: During PWM dimming, pin 2 of connector J3 should be left open. Also, the PWM signal must have the proper polarity with the positive connected to pin 1 of J3. Note that pin 3 of J3 is internally connected to the return path of the input voltage.Actual Size: 2.25” x 1.25”PWM DimmingV INTesting the Demo BoardNormal Operation: Connect the input source and the output LEDs as shown in the Connection Diagram and enable the board. The LEDs will glow with a steady intensity. Connect-ing an ammeter in series with the LEDs will allow measure-ment of the LED current. The current will be 350mA +/- 5%.Open LED test: Connect a voltmeter across the output ter-minals of the HV9930DB1. Start the demoboard normally, and once the LED current reaches steady state, unplug one end of the LED string from the demoboard. The output volt-age will rise to about 33V and stabilize.Short Circuit Test: When the HV9930DB1 is operating in steady state, connect a jumper across the terminals of the LED string. Notice that the switching frequency drops, but the average output current remains the same.PWM Dimming: With the input voltage to the board discon-nected, apply a TTL compatible, push-pull square wave sig-nal between PWMD and GND terminals of connector J3 as shown in the Connection Diagram. Turn the input voltage back on and adjust the duty cycle and / or frequency of the PWM dimming signal. The output current will track the PWMdimming signal. Note that although the converter operates perfectly well at 1.0kHz PWM dimming frequency, the best PWM dimming ratios can be obtained at lower frequencieslike 100 or 200HzTypical ResultsFig. 1 shows the efficiency plot f or the HV9930DB1 over the input voltage range. The converter has efficiencies greater than 80% over 13V input. Note that these measurements do not include the 0.3 - 0.5W loss in the reverse blocking diode.Fig. 2 shows the variation of the switching frequency over the input votage range. The frequency varies from 300kHz to 500kHz over the entire input voltage range and avoids the restricted frequency band of 150kHz to 300kHz and the AM band greater than 530kHz. This makes it easier to meet the conducted and radiated EMI specifications for the automo -tive industry.Fig.3 shows the output current variation over the input volt-age range. The LED current has a variation of about 2.0mA over the entire voltage range.7072747678808284Input Voltage (V)E f f i c i e n c y (%)300350400450500Input Voltage (V)S w i t c h i n g F r e q u e n c y (k H z )348.0348.5349.0349.5350.0350.5Input Voltage (V)O u t p u t C u r r e n t (m A )Fig. 3 Output Current vs. Input VoltageThe waveforms in Fig.4 show the drain voltage of the FET (channel 1 (blue); 10V/div) and the LED current (channel 4 (green); 100mA/div) at three different operating conditions – 9.0V in, 13.5V in and 16V in.Fig. 5 shows the operation of the converter during cold crank conditions as the input voltage decreases from 13.5V to 6V and increases back to 13.5V. In these cases, the input current reaches the limit set and the output current drops correspondingly. Thus, the LEDs continue to glow, but with reduced intensity. Once the voltage ramps back up, the out-put current goes back to its normal value and the converter comes out of the input current limit.Fig.6 shows the LED current during an input step change from 13.5 to 42V and back to 13.5V (similar to a clamped load dump). It can be seen that the LED current drops brieflywhen the input voltage jumps, but there are no overshoots.(a)(b)(c)Fig. 4. Steady State Waveforms(a): 9.0V in; (b): 13.5V in; (c): 16V inFig. 5.

In both cases, it can be seen that the HV9930DB1 can easily withstand faults and come back into normal operation almost instantly.Fig. 8 shows the PWM dimming performance of the HV9930DB1 with a 100Hz, 3.3V square wave signal. The converter can easily operate at PWM dimming duty cyclesfrom 1% - 99%.(a): Open LED Condition(b): Output Short CircuitFig. 7 HV9930DB1 during output fault conditionsFET drain voltage (20V/div)Channel 1 in (a); Channel 2 in (b)Channel 4 (green): LED currentShort Circuit(a)(b)(c)Fig. 8 PWM Dimming at 100HzChannel 1 (blue): PWM Dimming Input Signal (2V/div)Channel 4 (Green): LED current (100mA/div)Fig. 9 shows the rise and fall times of the output current dur-ing PWM dimming. The converter has nearly symmetric rise and fall times of about 25µs. These rise and fall times can be reduced (if desired) by reducing the output capacitance C10. However, this will lead to increased ripple in the output current.Conducted EMI Tests on theHV9930DB1In preliminary tests conducted on the demo board, the board meets SAE J1113 Class 3 conducted EMI standards without the need for any input filters (other than the input capacitors already included). This is a result of the combination of the continuous input current and a localized switching loop (Q1 – C1 – D3).Table 1 details the conducted EMI limit as per SAE J1113 and the maximum conducted EMI obtained from measure-ments on the board. The table also lists the Class of the SAE standard the board meets in each frequency range.The conducted EMI plots for the HV9930DB1 obtained at an input voltage of 13.5V and an LED string voltage of 27V(output current is 350mA) are given in the Appendix.

2 产品特性说明3 显示模式◆以下的显示模式表，涵盖了本产品所能支持的所有的显示模式；如果不在该表之的显示模式，产品不能确保正常工作。

◆该表已经覆盖我们大部分常用的显示模式，尤其是VESA标准定义的显示模式都在支持之列。

如果用户有要求显示一些特殊的显示模式，也可以根据用户提供的数据将其设置在支持之列。

◆并非每一个具体的应用都能处理显示模式表中的所有模式，需要根据PANEL的尺寸、分辨率以及一些关键参数进行选择。

◆ 大部分的PANEL都不支持垂直刷新率在75Hz以上的应用，这些模式A/D 板大多都能处理，但是应用高过PANEL限制的显示模式可能会导致PANEL损坏。

◆ 针对LCD显示器的特殊性，只有输入显示模式的分别率和PANE 显示分辨率相对应时，才会有最佳的显示性能。

例如大部分17寸PANEL的分辨率是1280×1024，那么只有输入的显示模式分辨率是1280×1024才会有最佳的显示效果。
