TPS23758 PoE Power Devices

Texas Instruments TPS23758 PoE Power Devices combine 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 TPS23758 features a high level of integration along with primary-side regulation (PSR), spread spectrum frequency dithering (SSFD), and advanced startup. This feature makes the TPS23758 an ideal solution for size-constrained applications. The PoE implementation supports the IEEE 802.3at standard as a 13W, Type 1 PD.
