Texas Instruments TPS23731 | Demoboard PMP22806
Class 4 PoE PD isolated-flyback converter (12 V, 2.1 A) primary side regulation reference design
Overview
| Topology | LAN / POE |
| Input voltage | 52.5-57 V |
| Output 1 | 12 V / 2.1 A |
Description
This reference design implements a Power over Ethernet (PoE) Power Device (PD) flyback converter with 12-V and 2.1-A output. TPS23731 PD and PWM controller provides all necessary functions to implement the PoE PD control and PWM control for the flyback converter. TPS23731 uses primary side regulation (PSR) that eliminates the need for optocoupler feedback.
Features
- Combined PD and PWM controller
- Primary side regulation (no optocoupler)
- Optional 48-V adapter input
- Frequency dithering for improved EMI
Typical applications
- Redundant Power Feeds or Power Sharing
- Barcode reader, WLAN, Wi-Fi® access point, IP network camera
- IP network camera
