Fully Integrated, 802.3af/at-Compliant PoE PD Interface with High-Efficiency PSR Flyback Controller Evaluation Board

Overview

TopologyLAN / POE
Input voltage36-57 V
Output 112 V / 2.1 A
IC revision1.0

Description

The EVL8009A-V-00A is an evaluation board designed to demonstrate the capabilities of the MP8009A, an integrated, IEEE 802.3af/at power over Ethernet (PoE) powered device (PD) power supply converter. It also includes a PD interface and a highly efficient flyback/forward controller.The PD interface features all IEEE 802.3af/at capabilities, including detection, 1-event classification, 2-event classification, a 120mA inrush current limit, an 840mA operation current limit, and a 100V hot-swap MOSFET.

Features

  • 36V to 57V Power over Ethernet (PoE)
  • Input or 48V Auxiliary Adapter Input
  • Primary-Side Regulation (PSR) for Flyback Applications
  • 802.3af/at Compliant
  • 250kHz Fixed Switching Frequency (fSW)
  • 32ms Soft-Start Time (tSS)
  • Frequency Dithering for Electromagnetic Interference (EMI) Reduction
  • Overload Protection (OLP), Short-Circuit Protection (SCP), and Over-Voltage Protection (OVP) with Hiccup Mode for Each Protection
  • Thermal Shutdown
  • Available in a QFN-28 (4mmx5mm) Package

Typical applications

  • Wireless Local Area Network (WLAN) Access Points
  • IEEE 802.3af/at-Compatible Devices, Security Cameras, Video Phones
  • PoE
