The PMP9730 reference design employs the UCC28051 power factor correction controller to implement a single stage PFC-Flyback AC/DC converter that generates an isolated 12V output at 3A from a universal AC input. The design features UCC28910 primary side regulation Flyback switcher for generating the VDD bias rails and the UCC24610 for 2ndary side synchronous rectification. This provides an excellent solution for systems such as motor drives requiring an isolated bus voltage, good power factor and high efficiency.
