Overview
| Topology | Flyback Converter |
| Input voltage | 85-135 V |
| Output 1 | 12 V / 1 A |
| Output 2 | 48 V / 0.4 A |
| IC revision | A |
Description
The PMP9727 reference design uses the UCC28740 flyback controller to generate both a 12V/1A and 48V/0.4A outputs from a 120V AC input. The valley switching of the UCC28740 allows this low-cost design to provide an efficiency of over 89%; no load losses are less than 80mW.
Features
- Peak efficiency approaches 90%
- Losses at no load are less than 80mW
- 120Vac input generates outputs of 12V/1A and 48V/0.4A
- Board length is approximately 64mm
- Test report is available
