HIGH POWER WHITE LED DRIVER WITH I2C INTERFACE

The STCF05 is a high efficiency power supply solution to drive multiple flash LEDs in camera phones, PDAs and other hand-held devices. The synchronous boost topology with output current control guarantees the proper LED current over all possible conditions of battery level and LED forward voltage. A ? Boost DC-DC converter with synchronous rectification\n? Drives 2 power white LEDs in series with a current up to 400 mA\n? Input voltage range 2.5 V to 5.5 V\n? Needs 3 external components only\n? Output current control\n? 1.8 MHz fixed frequency PWM control\n? Peak inductor current limited to 3 A;
