LD8116C-DS-00 May 2018

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

REV. 00

General Description

The LD8116C 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.
