White LED Driver
with Synchronous Boost Converter and PWM Brightness Control for up to 4 LEDs in Series
BD6072HFN
●General Description
BD6072HFN is boost DC/DC converter possible to boost output
voltage up to 18V (Max.) and drive the white LEDs at constant. It is possible that turning on white LED steadily by a series connection which has no current variation, and by a fast transient response with current mode. And, BD6072HFN is white LED driver IC with synchronous rectification. With synchronous rectification (no external schottky diode required) and small package, they can save mount space.
