The HV9911DB2 is an LED driver capable of driving up to twenty 100mA LEDs in series from an input of 9 - 16V DC. The demoboard uses Supertex’s HV9911 IC in a boost topology. The converter has a very good initial regulation, (+/-5%), and excellent line and load regulation over the entire input and output voltage range (<+/- 1%). The full load efficiency of the converter is typically greater than 85%.
