DESCRIPTION
The TPS23753 is a bined Power over Ethernet (Po E) powered device (PD) interface and current-mode dc/dc controller optimized specifically for isolated converter designs. The Po E implementation supports the IEEE 802.3at standard as a 13 W, type 1 PD. The requirements for an IEEE 802.3at type 1 device are a superset of IEEE 802.3-2008 (originally 802.3af) requirements.
The TPS23753 supports a number of input-voltage ORing options including highest voltage, external adapter preference, and Po E...
