General Description

The STCF06 is a high efficiency power supply solution to drive a single flash LED in camera phones, PDAs and other battery powered devices.

It is a buck-boost converter able to guarantee a proper LED current control over all possible conditions of battery voltage and LED forward voltage.

The output current control ensures a good current regulation over the forward voltage spread characteristics of the flash LED.
