Description

The PMP10994 reference design uses Buck converter to convert 120VAC input  to a 5V/35mA DC output with UCC28880 controller. With high side MOSFET integrated controller, the total component footprint has been minimized. The temperature rise of this board is less than 10oC at room temperature.

Features
  • 120VAC input to 5V/35mA output
  • No customer magnetic applied
  • MOSFET integrated PSR controller applied on Buck topology
  • Less than 10degC temperature rise on the controller at full load
  • Test report is available
