iW1782 - AC/DC Digital Quasi-Resonant PWM Controller
Description
The iW1782 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 iW1782 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 iW1782 is optimized to work with Dialog’s iW636 secondary-side controller for Qualcomm® Quick Charge™ 3.0 (QC3.0) technology, to achieve fast and smooth voltage transition upon request by mobile devices (MD).

Rapid Charge™ AC/DC Digital Quasi-Resonant PWM Controller
1 Description
The iW1782 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. The device operates in quasi-resonant mode to provide high efficiency and a number of key built-in protection features. The iW1782 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 iW1782 is optimized to work with Dialog’s iW636 secondary-side controller for Qualcomm® Quick Charge™ 3.0 (QC3.
