Flexible Dimming Solution by PWM / 0-10V / Potentiometer
The LD8116A contains a processor which can convert the three different inputs of dimmer include 0 to 10V DC potential,
0 to 100% duty cycle PWM (pulse width modulation) signal and potentiometer become a PWM signal output.
It is easy to provide the isolation dimming control via optocoupler 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 IC is available in a small SOT-26 SMD package, LD8116A GL, to minimize PCB size as well as component counts.
