iW3631 Description
The iW3631 is a two-stage, high-performance AC/DC offline power supply controller for dimmable LED luminaires with an analog dimming interface. It controls the LED current based on an analog input voltage on the dimming pin. It has a built-in 0-10V dimming interface that works directly with 0-10V dimming systems, eliminating the need for a driver circuit and microcontroller.
