BD6072HFN
White LED Driver with Synchronous Boost Converter and PWM Brightness Control for up to 4 LEDs in Series

Switching Regulator type LED Driver Series for small LCD backlight are boost DC/DC converters possible to 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. With synchronous rectification (no external schottky diode required) and small package, they can save mount space.
