WHITE LED STEP-UP CONVERTER

Description

Pin Assignments

(Top View)

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

OVP

connected multiple strings of equal number of LEDs.

SOT26 / TSOT23-6

DFN2020C-6

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.
