USB Type-C DFP Charger 5V3A SSR Control Adapter Reference Design


Design files


The PMP4403 is an AC in 5V 3A reference design for USB Type-C™ DFP charger 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.

  • S.R QR flyback with secondary side regulation
  • <30mW standby power
  • 15W USB Type C DFP + BC1.2
  • Compliant with DoE Level VI and EU CoC V5 tier-2 standards
  • Fully tested and passed EN55022 Class B conducted and radiated EMI
