AP5724 Product details

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.For driving higher number of LEDs, AP5724 also supports a single feedback of parallel connected GND 2 5 OVP multiple strings of equal number o
