Datasheet Summary
Off-line LED Driver Controller Supports Wide Range of PWM Dimming Interfaces
1 Description
The iW3637 is a high-performance AC/DC power controller optimized for non-isolated buck or isolated flyback converter applications to step-down a high-voltage DC input to drive LEDs in SSL lighting applications. A converter designed with the iW3637 can work with a DC input voltage from a front-end, off-line boost converter to minimize low frequency output ripple current, and virtually eliminate all flicker in the system. It uses Renesas’ PrimAccurate™ advanced sensing technology to achieve excellent output current regulation without the need for direct voltage or current feedback ponents....
