Flexible Dimming Solution by PWM / 0-10V / Potentiometer
REV. 01
General Description
The LD8116B 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 LD8116B is the SOT-26 package to minimize the PCB
size as well as component counts.

FUNCTION
Supply voltage pin.
Ground or Power return pin.
This pin is dimming output. It’s an open-drain configuration.
Connect this pin to power supply by a resistor.
This pin is used to set bias current of DIM pin by a resistor
(= RISET)connected between this pin and GND.
This pin is used to set minimum output clamped duty cycle by a
resistor (= RCLAMP)connected between this pin and GND.
Dimming signal input;
- Voltage Potential : 0/1V to 10V
- PWM Dimming : 0.2k to 10kHz and amplitude is upper 3.2V
- Potentiometer : 0 to 100k ohm
