Description

This evaluation board is based on the STCF01,

that is a white LED driver optimized for driving two

to four LEDs from a Li-Ion battery input.

It provides up to 300 mA over an input voltage

range of 2.6 V to 5.5 V and it features 16.5 V

output voltage, 1.5 MHz internal power switch,

internal soft start, open load voltage protection

and optimized internal compensation.

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 STCF01 is ideal for camera flash in cellular

phones requiring, small circuit size and very high

efficiency (up to 90%).
