支持s 0-10V Analog, PWM, Resistor Dimming

The iW337 is a secondary-side PWM signal generator that works with three types of dimming inputs: PWM dimming, 0-10V linear dimming, or simple dimming using a single resistor to ground from the DIM pin. The iW337 converts any of these three signals into a 1%–100% PWM duty cycle that provides a dimming signal to a primary-side LED driver such as theIW3631.，消除了对变压器或其他驱动电路的需求。
