Type-3 IEEE802.3bt-ready flyback converter PoE powered device reference design
Details
| Topologie | Sperrwandler |
| Eingangsspannung | 42-57 V |
| Ausgang 1 | 12 V / 4.25 A |
| IC-Revision | A |
Beschreibung
This design showcases a low cost, Type-3, Class 6, 51W flyback converter for powered devices through Power over Ethernet. The TPS2373-3 PD controller provides detection and classification while also powering up the LM51551-Q1 PWM controller through its advanced startup feature. This design takes in a 42V-57V PoE input and outputs a 12V rail for applications such as IP network cameras and wireless access points.
Eigenschaften
- Supports power levels for IEEE802.3bt Type 3
- Isolated diode rectified flyback design
- Built in hiccup mode protection for superior thermal performance during faults
- PD Advanced Startup for PWM controller
- Automatic Maintain Power Signature (MPS)
- Oring circuit for auxiliary power through AC/DC
Typische Anwendungen
- IP Network Cameras, Wireless Access Points
- Other >25-W PoE PD Design
