FLEXIBLE 0 TO 10V DIMMING SIGNAL INTERFACE CONTROLLER

Description

Pin Assignments

The AL8116 is a flexible dimming signal interface controller that can

convert the three different inputs of dimmer type including 0 to 10V

DC linear dimming, 0 to 100% duty cycle PWM (pulse width

modulation) signal and a simple resistive potentiometer to an output

PWM signal. It is easy to provide an isolation dimming control via an

opto-coupler to the primary side LED driver.

The AL8116 has a wide input voltage range from 10V to 56V. The

DIM pin of the AL8116 can output an adjustable accurate bias current

that make it suit for both active and passive 0 to 10V dimmers,

meanwhile potentiometers. The AL8116 output duty cycle accuracy is

typically ±2.5% and the minimum output duty cycle can be set through

SOT26 (Type CJ)

the CLAMP pin resistor.

The AL8116 has an internal auto-recoverable over-temperature-

protection.

The AL8116 is available in SOT26 (Type CJ) package to minimize

PCB space as well as external component count.
