AL8116 Typical Applications Circuit
LED+ 5V PWM LED- VCC DDIM RDIM VCC DIM 0 to 100kΩ C 0V
AL1665
DIM GND CLAMP
AL1666
RL RCLAMP R 0 to 10V OPTO PWM OUT ISET
AL8116
RISET GND
Figure 1. AL8116 Typical Application Circuit Pin Descriptions Pin Number Pin Name Function
1 VCC Supply voltage pin. 2 GND Ground or Power return pin. This pin is dimming output. It’s an open-drain configuration. 3 OUT Connect this pin to power supply by a resistor. This pin is used to set bias current of DIM pin by a resistor 4 ISET (RISET) connected between this pin and GND. This pin is used to set minimum output clamped duty cycle by a resistor 5 CLAMP (RCLAMP) connected between this pin and GND. Dimming signal input; - Voltage Potential: 0/1V to 10V 6 DIM - PWM Dimming: 0.2k to 10kHz and amplitude is upper 3.2V - Potentiometer: 0 to 100k
