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
