AL8116
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. (Top View) VCC 1 6 DIM GND 2 5 CLAMP OUT 3 4 ISET 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-temperatureprotection.
The AL8116 is available in SOT26 (Type CJ) package to minimize
PCB space as well as external component count. Applications Features Wide VCC Operating Range 10V to 56V
