Texas Instruments UCC28051/UCC25600/UCC28710 | Demoboard PMP9531
350W PSU with Universal AC Input and 28V Output - Reference Design
Overview
| Topology | Power Factor Correction |
| Input voltage | 85-265 V |
| Output 1 | 28 V / 12.5 A |
| IC revision | D |
Description
High efficiency, high power factor and reliable power supply are the main focus of the PMP9531 design for motor driver applications. Transition mode (TM) power factor correction (PFC) with UCC28051 and LLC series resonant converter (SRC) with UCC25600 are applied in PMP9531. In addition, a high-side buck converter with UCC28710 is applied here as the bias supply. 93% converter efficiency is achieved at high line while still obtaining 90% converter efficiency at low line.
Features
- Universal 85VAC-264VAC input
- 28V 350W output
- Up to 93% converter efficiency
- TM PFC output power goes up to 385W
- AC-DC PSR buck for bias supply
