AC/DC Buck Converter Reference Design with Low Line Input and 12V/25mA Output

PMP20654

Design files

Overview

The PMP20654 reference design uses Buck converter to convert low line AC input voltage (85Vac to 140Vac) to a 12V/25mA DC output with UCC28880 FET integrated controller. This design passes class B conducted emission test without adding any EMI filter before rectifier.

Features
  • 85VAC - 140VAC to 12V/25mA
  • Single-layer PCB
  • Pass Class B conducted emission test
  • Less than 10°C temperature rise at toom temperature
