AP5724 Description
Pin Assignments The AP5724 is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current. The device can drive 2 ~ 6 (Top View) LEDs in series from a Li-Ion cell. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and SW 1 6 VIN eliminates the need for ballast resistors.
