Step Up Converter For Camera Flash Light

STCF01 is a dedicated IC to drive up to four white LEDs with constant current in camera Flash for cellular phones. It provides up to 300mA over an input voltage range of 2.6V to 5.5V. A high switching frequency (1.5MHz) allows the use of tiny surface-mount components, as well as the use of current levels set resistors. Only an inductor, a Schottky Diode two capacitors and two resistors are required. Besides, a low output ripple is guaranteed by the current mode PWM topology and by the use of low E.S.R. SMD ceramic capacitors. The device is also thermal protected and available in QFN 3x3mm 10L package.
