LED Application Product : 3 in 1 Signal Processor

LD8116D

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

The LD8116D 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.
