STCF03 Datasheet (STMicroelectronics) - High power white LED driver

STCF03, High power white LED driver

The STCF03 is a high efficiency power supply solution to drive a single flash LED in camera phone, PDAs and other hand-held devices.

It is a buck - boost converter to guarantee a proper LED current control over all possible conditions of battery voltage and output voltage; the output current control
