The LD8116A 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 LD8116A is the SOT-26 package to minimize the PCB size as well as component counts.
