STCF06 WHITE LED DRIVER WITH I²C INTERFACE
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
