Texas Instruments TPS23730 | Demoboard PMP23365
24V, 3A Class 8 PoE PD reference design with external hot swap and telemetry
Overview
| Topology | LAN / POE |
| Input voltage | 24 V |
| IC revision | B |
Description
This reference design implements a Power-over-Ethernet (PoE) power device (PD) active-clamp forward converter with 24V and 3A output. A TPS23730 PD with integrated pulse-width modulator (PWM) controller provides the necessary functions for the PoE PD and PWM control for the active-clamp forward converter. This design uses secondary-side regulation (SSR) with an optocoupler feedback. An external hot swap is added to enable Class-7 and 8 PD applications. INA237 is used on the primary side to monitor the DC/DC input voltage and current, and the power information is sent to the secondary side by either I2C isolator or optocoupler-based circuits.
Features
IEEE 802.3bt Type 3 compliant PoE PDIntegrated PWM controller for flyback or active clamp forward configurationFrequency dithering for EMI reductionSoft-start control with advanced start-up and hiccup mode overload protectionSoft-stop shutdownOptional adapter input
