DESCRIPTION

The EV1527DR-02A evaluation board is designed to drive a single Lumileds LED with low, forward voltage for Camera Flash applications. The board is set up to obtain 150mA torch current and 750mA flash current with an input voltage range of 3.0V to 4.2V. The torch and flash currents can be adjusted by resistors R2 and R3 on the Evaluation Board.
