Featured reference designs and tools
The PMP8965 is a 12.5W USB adapter reference design using the UCC28740 quasi-resonant/discontinues flyback controller, with synchronous rectification to improve efficiency using the UCC24610 green rectifier controller.
The UCC24612-1EVM evaluation module (EVM) is used to convert the output rectifier of a flyback converter from a diode to a synchronous rectifier (SR) FET to investigate and evaluate the efficiency benefits of using an SR over a rectifier diode.
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.
