iW1781 Product details

Description

The iW1781 is a high performance AC/DC power supply controller for rapid charge that uses digital control technology to build peak-current mode PWM flyback power supplies.

Features

The iW1781 can achieve tight multi-level constant voltage and multi-level constant current regulation without a traditional secondary-feedback circuit. It also eliminates the need for loop compensation components while maintaining stability over all operating conditions. The iW1781 supports USB Power Delivery (USB PD) and other proprietary rapid charging protocols with secondaryto-primary digital communication handled by secondary-side rapid charge interface circuits, including third party ICs.
