Description

The PMP20533 power reference design provides up to 15 V/45 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.  The TPS25740A provides the interface between the flyback power supply and the Type-C cable. The PMP20533 has been certified as a power brick by the USB-IF (Product Test ID: 1020017).

Features
  • 91% average efficiency
  • Standby (no load) power consumption is less than 30mW
  • High power density, greater than 12W per cubic inch
  • Compact form factor 45mm x 28mm (1.8" x 1.8" x 1.1")
  • Conducted emissions are below Class B levels
