PX15122S Single Channel LED Constant Current Driver

SKU PX15122S Category

The PX15122S is a single channel LED constant current driver which adopts constant current control technology. Built-in output current 19.5mA (default), also adjustable through the external resistor Rext (19.5mA~150mA), and the output current is not varied with the variation of the OUT voltage and environment temperature. The cost is low due to simple structure and fewer peripheral components.

The PX15122S can implement dimming via PWM signals through DIM port.
