USB-C DFP 5V3A SSR Control Adapter Reference Design

Overview

TopologyFlyback Converter
Input voltage90-264 V
Output 15 V / 3 A
IC revisionA

Description

The PMP4403 is an AC in 5V 3A reference design for USB Type-C™ DFP applications. It also is compliant with BC 1.2 devices. The solution is a synchronous rectified QR flyback which uses the UCC28740 and UCC24636. Good regulation and dynamic performance is achieved by using a secondary side regulation controller UCC28740. Also Volt-Second balancing SR controller UCC24636 is adopted in the design to improve the efficiency. The solution easily exceeds DoE Level VI and EU CoC V5 Tier-2 standards.
