IW3631-00 - Renesas Electronics
Description: The iW3631 two-stage LED driver is a dimmable digital offline PWM controller for solid-state lighting applications up to 120W with high power factor (PF >0.95) and low THD (<10%). It features a built-in driver for isolation transformers that enables direct, 0-10V dimming without the need for an external MCU and driver circuit, reducing cost and complexity. The iW3631 can also be implemented to support a PWM dimming interface to simplify use in wireless SSL applications.The iW3631 operates in a quasi-resonan
