Key Document


PMP11236 is a high voltage (105VAC to 440VAC) Buck converter reference design using MOSFET integrated controller UCC28881. 24V/100mA is provided by the UCC28881 Buck converter and followed by a TLV70450 LDO to provide 5V/20mA output. This design is compatible with Class B conduction EMI regulation.

  • 105VAC to 440VAC high voltage input
  • Buck converter with MOSFET integrated controller
  • 24V/100mA and 5V/20mA outputs
  • Conduction EMI verified and test data included
  • Board dimension: W x L = 20mm x 45mm
  • No custom magnetic applied
