TPS23755 PoE DC-DC Controllers

Texas Instruments TPS23755 PoE DC-DC Controllers integrate 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. The TPS23755 is an ideal solution for size-constrained applications with a high integration level, primary side regulation (PSR), spread spectrum frequency dithering (SSFD), and an advanced startup. The PoE implementation supports the IEEE 802.3at standard as a 13W, Type 1 PD.
