Texas Instruments TPS23730 | Demoboard PMP23253
Class 6, PoE, PD, 15-V 3.3-A active-clamp forward converter reference design
Details
| Topologie | LAN / POE |
| Eingangsspannung | 37-57 V |
| Ausgang 1 | 15 V / 3.3 A |
| IC-Revision | A |
Beschreibung
This reference design implements a Power over Ethernet (PoE) power device (PD) active-clamp forward converter with 15-V and 3.3-A output. A TPS23730 PD with integrated Pulse Width Modulator (PWM) controller provides the necessary functions to implement the PoE PD control and the PWM control for the active-clamp forward converter. This design uses Secondary-Side Regulation (SSR) with an optocoupler feedback.
Eigenschaften
- IEEE802.3bt Type 3 compliant PoE PD
- Integrated PWM controller for flyback or active-clamp forward configuration
- Frequency dithering for EMI reduction
- Soft-start control with advanced startup and hiccup mode overload protection
- Soft-stop shutdown
- Optional adapter input
Typische Anwendungen
- Video and VoIP Telephones, Access Points, Security Cameras, Pass-through System
- Redundant Power Feeds or Power Sharing
