IW662-03-SO8

Power Supply Controllers, Monitors Overview

The IW662-03-SO8 is an integrated secondary-side synchronous rectifier controller and RapidCharge interface IC designed for Qualcomm Quick Charge 3.0 and 2.0 applications. It utilizes 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, reducing power loss during transitions without requiring a parallel Schottky diode. Operating within a temperature range of -40°C to +125°C, it supports low BOM cost solutions in SOIC-8 packages.
