Texas Instruments UCC28742 | Demoboard PMP31087

Description

This reference design uses the UCC28742 flyback controller to generate two outputs (12 V at 2.2 A and 3.3 V at 1.5 A) from a universal input. UCC28742 uses an optical coupler to regulate the output and improve transient response. The valley-switching technique reduces switching losses and keeps the efficiency high.

Features

• Resonant-ring valley-switching operation
• Dual isolated outputs consisting of 12 V at 2.2 A and 3.3 V at 1.5 A
• Universal AC-input voltage range of 85 VAC to 265 VAC
• Output over-voltage and over-current protection
• Complete tested design with available design files and test report

Typical applications

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