General Description

The LD8116Q 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 LD8116Q is the SOT-26 package to minimize the PCB

size as well as component counts.
