Class 6 Power over Ethernet PD with 24V 2.5A active-clamp forward converter reference design

Overview

TopologyLAN / POE
Input voltage37-57 V
Output 124 V / 3 A
IC revisionA

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 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

Typical applications

  • Machine vision camara
