说明

• Typical Application for AP5725 Step-Up White LED Driver. The AP5725 is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current. The device can drive 2 - 6 LEDs in series from a Li-Ion cell. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminates the need for ballast resistors. For driving higher number of LEDs, AP5725 also supports a single feedback of parallel connected multiple strings of equal number of LEDs
