ee Finish/RoHS Compliant (Note 1) Gener al Description The AP5724 is a step-up DC/DC converter specifically designed t o drive white LEDs with a constant curr ent. The device can drive 2~6 LEDs in s eries from a Li-Ion cell. Series connec tion of the LEDs provides identical LED currents resulting in uniform brightne ss and eliminates the need for ballast resistors. The AP5724 switch
