IW1782-00

AC DC Converters, Offline Switchers Overview

The iW1782-00 is a high-performance AC/DC power supply controller designed for rapid charge applications, utilizing digital control technology to build peak current mode PWM flyback power supplies. It supports Qualcomm Quick Charge 3.0 (QC3.0) technology, providing output voltages from 3.6V to 12V in 200mV increments with user-selected current limit combinations. The device features proprietary secondary-to-primary digital communication and a built-in decoder, eliminating discrete decoders on the primary side. It employs a single optocoupler for all rapid charge information, including output voltage request, current limit, undershoot, and overvoltage protection.
