Texas Instruments UCC28740DR | Demoboard PMP11451

USB-C DFP, 20V/3A Out, Universal AC Input Reference Design

Overview

TopologyFlyback Converter
Input voltage85-265 V
Output 120 V / 3 A
IC revisionD

Description

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.

Features

91% average efficiencyStandby (no load) power consumption is less than 40 mWConducted emissions are below Class B levelsCompact form factor 60 mm x 60 mm x 25 mm (2.35 in x 2.35 in x 1 in)
