166VAC to 528VAC Input, 5V & 24V Dual-output Reference Design with Cascode-MOSFET Configuration


Design files


The PMP11302 is a high voltage (166VAC to 528VAC) Buck converter design using UCC28881 with an series connected external MOSFET to achieve high voltage conversion ratio. 24V/100mA is provided by the UCC28881 Buck converter and followed by a TLV70450 LDO to provide 5V/20mA output.

  • 166VAC to 528VAC high voltage input
  • Buck converter with cascode-MOSFET
  • 24V/100mA and 5V/20mA outputs
  • Test data included
  • Board dimension: W x L = 38mm x 45mm
