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. This design is USB-IF certified as a captive-cable power brick.

Features
  • 91% average efficiency
  • Standby (no load) power consumption is less than 40 mW
  • Conducted emissions are below Class B levels
  • Compact form factor 60 mm x 60 mm x 25 mm (2.35 in x 2.35 in x 1 in)
