Description

This reference design is a 12-V/5-A and 50-V/1-A isolated dual-output auxiliary power supply. Secondary-side regulation improves the line and load regulation using UCC28742. DCM valley-switching operation enable higher efficiency at light load. All components height below 20 mm enable slim TV application.

Features

  • Valley-switching enable higher efficiency at light load
  • Higher integrated protection simplifies the bom cost and save space
  • Components height is below 20 mm to enable slim TV application

Typical applications

  • Smart Electricity Meters
  • Industrial and Medical AC-to-DC Power Supplies / Bias Supply for UPS, Server PSU
  • Power Supply for Cable Modem, Television, Set-Top Box, and Wireless Routers
  • AC-to-DC Power Supply for Appliances
