Texas Instruments Evaluation Module for TPS23756 TPS23756EVM TPS23756EVM Scheda Tecnica

This user’s guide describes the TPS23756 evaluation module (TPS23756EVM). The TPS23756EVM
contains evaluation and reference circuitry for the TPS23756. The TPS23756 integrates a powered-device
(PD) controller and power-supply controller targeted at high-power, wide input range, isolated converter
topologies. The TPS23756 is compliant with the IEEE 802.3at Power over Ethernet (PoE) standard.
