HV9911DB3 - High Brightness Step-Down LED Driver Demoboard (HV9911DB3)

The HV9911DB3 is an LED driver capable of driving up to 25 one-watt LEDs in series from an input of 130 - 200VDC. Thedemoboard uses HV9911 in a buck topology with theHV7800 used for high side current sensing. The converter hasa very good initial regulation (+/-5%) and excellent line and loadregulation over the entire input and output voltage range (<+/-2%). The full load efficiency of the converter is typically greaterthan 85%.
