AP5726 WHITE LED STEP-UP CONVERTER Description Pin Assignments The AP5726 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, AP5726 also supports a single feedback of parallel connected multiple strings of equal number of LEDs. The AP5726 switches at 1.2MHz that allows the use of tiny external components. A low 0.31V feedback voltage minimizes power loss in the current setting resistor for better efficiency.
