说明
- HV9911DB3, Demo Board is an LED driver capable of driving up to 25 one-watt LEDs in series from an input of 130 - 200VDC. The demo board uses HV9911 in a buck topology with the HV7800 used for high side current sensing. The converter has a very good initial regulation (+/-5%) and excellent line and load regulation over the entire input and output voltage range (<+/-2%). The full load efficiency of the converter is typically greater than 85%
