Product details

Description

The iW1790 is a high performance AC/DC power supply controller for rapid charge that uses main transformer communication (XM-Comm) technology to minimize external component count and simplify system design.

Features

The iW1790 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 iW1790 is optimized to work with Dialog’s iW660/2/3 secondary-side controllers for various rapid charge protocols, such as Samsung Adaptive Fast Charge (AFC) (iW660), Qualcomm® Quick ChargeTM 2.0 and 3.0 (QC2.0: iW660/2/3;.
