Texas Instruments UCC28742 | Demoboard PMP31087
31-W offline valley-switching flyback with multiple outputs reference design
Overview
| Topology | Flyback Converter |
| Input voltage | 85-265 V |
| Switching frequency | 80 kHz |
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
