Texas Instruments TPS23730 | Demoboard PMP23365
Class 6 Power over Ethernet PD with 24V 2.5A active-clamp forward converter reference design
Overview
| Topology | LAN / POE |
| Input voltage | 37-57 V |
| Output 1 | 24 V / 3 A |
| IC revision | A |
Description
This reference design implements a Power over Ethernet (PoE) power device (PD) active clamp forward converter with 24V and 2.5A output. A TPS23730 PD with integrated pulse width modulator (PWM) controller provides all 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.
Features
- IEEE 802.3bt 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 start-up and hiccup mode overload protection
- Soft-stop shutdown
- Optional adapter input
Typical applications
- Machine vision camara
