IEEE 802.3at PoE Interface with Wide Range High Efficiency DC-DC Controller

Overview

TopologyFlyback Converter
Input voltage0-57 V
Switching frequency225-275 kHz
Output 15 V / 5 A

Description

The Texas Instruments TPS23752EVM-145 evaluation module (EVM) helps designers evaluate the performance of the TPS23752 IEEE 802.3at PoE Interface and Green-mode DC/DC Controller. The EVM contains input and output connectors as well as control jumpers to ease evaluation of device features.

Features

  • High-efficiency synchronous-flyback design including enhanced light-load operation (with synchronous rectifier disable and variable frequency operation)
  • Sleep mode capability including PSE DC and Pulsed MPS signature, wake, and status LED
  • 24- and 48-V adapter input capability
  • Gigabit Ethernet pass-through interface
  • IEEE 802.3at type-2 hardware classification with secondary side status flag (T2P) and LED
  • Robust 100-V, 0.5-Ω, internal-hotswap MOSFET
  • 5-V, 5-A, 25-W dc output

RemarksL1=3.3uHL2=0.33uHReffer page no.5
