LD8116QL-DS-00 July 2020

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

REV. 00

General Description

The LD8116QL contains a processor which can convert

the three different inputs of dimmer type include DC

potential, 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 15V to

56V, adjustable bias current source for potentiometer and

high precision LED dimming current.

The LD8116QL is the SOT-26 package to minimize the

PCB size as well as component counts.
