WhiteLEDDriver

with Synchronous Boost Converter

and PWM Brightness Control for up to 4 LEDs in Series

BD6076GUT

●General Description

●Key Specifications

The BD6076GUT is a white LED driver IC with

synchronous rectification that can drive up to 4LEDs.

With synchronous rectification (no external schottky

diode required) and small package, they can save

mount space.
