USB-IF certified USB Type-C™ DFP 20V/3A/60W output, universal AC input reference design

PMP11451

Overview

This power reference design provides up to 20 V/60 W over USB Type-C from a universal AC input range of 85 to 265 VAC for charger applications. The UCC24636 synchronous rectifier driver allows this design to provide 91% average efficiency. A daughter card provides the PD port control over the USB Type-C output connector. The required companion daughter card for this reference design is PMP11455. This design is USB-IF certified as a captive-cable power brick.

characteristic
