General 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 components.

Key Features
