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.

All the functions of the device are controlled

through the I²C bus which helps to reduce logic

pins on the package and to save PCB tracks on

the board. Hard and soft-triggering of flash are

both supported. The device includes many

functions to protect the chip and the power LED,

such as: soft start control, chip over temperature,

open and shorted LED detection and protection.
