Texas Instruments UCC28781-Q1 | Demoboard PMP23195
19-W, AC/DC multioutput 5-V and 12-V ZVS flyback reference design for server applications
Overview
| Topology | Flyback Converter |
| Input voltage | 90-265 V |
| Switching frequency | 500 kHz |
| Output 1 | 12 V / 1.5 A |
| Output 2 | 5 V / 0.2 A |
| IC revision | A |
Description
This reference design converts a universal AC input to an isolated 12-V, 1.5-A output and an isolated 5-V, 0.2-A output. The design achieves a peak efficiency of 92.7%. This reference design features UCC28781-Q1 which is a zero-voltage switching (ZVS) flyback controller to minimize switching losses, UCC5350, a reinforced isolated gate driver to drive the synchronous rectifier MOSFET and TPS629203, a synchronous buck converter with low quiescent current.
Features
- Peak efficiency of 92.7%
- ZVS on primary side
- Synchronous rectification to minimize conduction loss on 12-V output
Typical applications
- Medical PSU
- Industrial AC/DC
