IW662-05-SO8

Power Supply Controllers, Monitors Overview

The iW662-05-SO8 is an integrated secondary-side synchronous rectifier controller and rapid charge interface IC designed for Qualcomm Quick Charge 3.0 and 2.0 applications. It utilizes Renesas' XM-Comm technology to communicate with primary-side controllers (iW1790, iW1796, iW1798), eliminating optocouplers. The device integrates a synchronous rectifier controller with adaptive off-time control to remove parallel Schottky diodes. It features high-voltage drain sensing up to 100V without external clamping circuits and lossless MOSFET VDS sensing for timing control.
