TPS23755 Overview
The TPS23755 device bines 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 high level of integration along with primary side regulation (PSR), spread spectrum frequency dithering (SSFD), and advanced startup makes the TPS23755 an ideal solution for size-constrained applications. The PoE implementation...
