The HV9911DB4 is an LED driver dempboard capable of driving one to six three-watt LEDs in series from an input of 9.0 - 16VDC. The demoboard uses HV9911 in a SEPIC topology to drive LED string voltages higher or lower than the input voltage. 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%.
