Description

This reference design is a simple, low-cost high side Buck converter to convert universal AC input voltage (85Vac to 265Vac) to a non-isolated 22V/250mA DC output with UCC28710 controller.

Features
  • Universal AC Input (85Vac to 265Vac)
  • Small 14.6mm2 two layer PCB footprint
  • Greater than 76% full-load efficiency at high line
  • <1% voltage regulation across line and load
