HM6281 Overview
The HM6281 regulator is fixed frequency PWM Boost (step-up) LED constant current driver, capable of driving Series 1W LED units with excellent line and load regulation. The regulator is simple to use because it includes internal frequency pensation and a fixed-frequency oscillator so that it requires a minimum number of external ponents to work. The HM6281 could directly drive 5~8 Series 1W LED units at VIN>12V.
