TPS23755 - IEEE 802.3at PoE PD

Description

The TPS23755 device combines a Power over Ethernet (PoE) powered device (PD) interface, a 150V switching power FET, and a current-mode DC-DC controller optimized for flyback topology.

Features

  • Complete IEEE 802.3at PD solution for type 1 PoE.
  • Ethernet Alliance (EA) logo certified designs available.
  • Robust 100-V, 0.36-Ω (typ) hotswap MOSFET.
  • Programmable classification level.
  • Integrated PWM controller with 0.77-Ω (typ) 150-V power MOSFET.
  • Flyback controller with PSR.
  • Supports CCM operation with secondary side diode rectifier.
  • ±3% (typ, 12-V Output) Load regulation (5%-100% range).
  • Supports low-side switch.
