LD8116B-DS-01 August 2018

Flexible Dimming Solution by PWM / 0-10V / Potentiometer

REV. 01

General Description

The LD8116B contains a processor which can convert the

three different inputs of dimmer type include 0~10V DC

potential, 0~100% duty cycle PWM (Plus Width Modulation)

signal and potentiometer become a PWM signal output. It

is easy to provide the isolation dimming control that via

opto-coupler for smart LED lighting application.

The device features include wide input voltage from 13V to

58V, adjustable bias current source for potentiometer and

high precision LED dimming current.

The LD8116B is the SOT-26 package to minimize the PCB

size as well as component counts.
