支持0-5V和0-10V模拟，PWM，电阻调光

The iW330 is a secondary-side PWM signal generator that works with three types of dimming inputs: 0-5V and 0-10V PWM dimming, 0-5V and 0-10V 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%–100% PWM duty cycle output that provides a dimming signal to a primary-side LED driver such as theiW3636, eliminating the need for transformers or other driver circuitry.
