IW662-01-SO8

Power Supply Controllers, Monitors Overview

The IW662-01-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 such as the iW1790, iW1796, or iW1798, eliminating optocouplers. The device features adaptive off-time control for synchronous rectification, removing the need for parallel Schottky diodes. It operates within a temperature range of -40°C to +85°C and is housed in an SOIC-8 package with a pitch of 1.27 mm.
