BD6071HFN
White LED Driver with Synchronous Boost Converter and PWM Brightness Control for up to 3 LEDs in Series
BD6071HFN
White LED Driver with Synchronous Boost Converter and PWM Brightness Control for up to 3 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. BD6071HFN suited over voltage and over current limit from BD6072HFN.
