Texas Instruments TPS2379 | Demoboard PMP7499
Non-Standard (>25.5W) PoE - High Efficiency Forward Converter (12V@5A) Reference Design
Details
| Topologie | Eintaktflusswandler |
| Eingangsspannung | 42-57 V |
| IC-Revision | B |
Beschreibung
This converter provides a high power PoE output of 12V/5A. The TPS2379 PD controller allows the use of an external hot swap FET for increased efficiency. The UCC2897A PWM controller is used to implement a high efficiency active clamp forward converter.Remark: BOM & Test-Result are added with schematic.
Eigenschaften
- High efficiency (90% with PoE supply, 93.6% with adapter supply)
- 12V at 5A output
- Isolated Forward with synchornous rectifier
- Uses TPS2379 combined with UCC2897A to implement a high efficiency active forward converter
- Allows an external hot swap FET for increased efficiency
- This circuit design is full-functional tested and recommended for new designs
Typische Anwendungen
- IP Camera
