iW3630 Overview
The iW3630 is a two-stage, high-performance AC/DC offline power supply controller for dimmable LED luminaires with analog dimming interface. It controls LED current based on analog input voltage on the dimming pin. It also has a built-in 0-10V isolation transformer driver which can work directly with 0-10V dimming system without adding extra driver circuit and micro-controller.
