Detailed Description

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 the CLAMP pin resistor.

The AL8116 has an internal auto-recoverable over-temperatureprotection. The AL8116 is available in SOT26 (Type CJ) package to minimize PCB space as well as external component count.
