Texas Instruments TPS23730 | Demoboard PMP22477
Class 6 PoE PD flyback converter (12 V, 3.8 A) with input-power limiting and PSR reference design
Details
| Topologie | Sperrwandler |
| Eingangsspannung | 42.5-57 V |
| Ausgang 1 | 12 V / 3.8 A |
Beschreibung
This reference design implements a Power over Ethernet (PoE) Power Device (PD) flyback converter with 12-V and 3.8-A output. TPS23730 PD and PWM controller provide all necessary functions to implement the PoE PD and PWM control for the flyback converter. TPS23730 uses primary side regulation (PSR), eliminating the need for optocoupler feedback. An input power-limiting circuit enables the output to be paralleled with a second converter for increased output-power capability.
Eigenschaften
- Combined PD and PWM controller
- Primary side regulation (no optocoupler)
- Input-power limiting
- Converters can be paralleled for increased power
Typische Anwendungen
- Occupancy detection (people tracking, people counting), WLAN/Wi-Fi access point, Vision sensors, Barcode reader
