iW662 Overview
The iW662 is an AC/DC secondary-side bo controller for Qualm® Quick ChargeTM 3.0 (QC3.0) which includes USB interface, secondary-to-primary munication and synchronous rectification functions in a single IC. The iW662 resides on the secondary side of an AC/DC power supply and allows the adapter to be configured for multi-level output voltages from 3.6V to 12V in 200mV increments, depending on the voltage requested by...
