Overview
Description
The iW330 is a secondary-side PWM signal generator that works with three types of dimming inputs: 0V to 5V and 0V to 10V PWM dimming, 0V to 5V and 0V to 10V linear dimming, or simple dimming using a single resistor to ground from the DIM pin. The iW330 converts any of these three signals into a 5% to 100% PWM duty cycle output that provides a dimming signal to a primary-side LED driver such as the iW3636, eliminating the need for transformers or other driver circuitry.
