DESCRIPTION
The TPS23757 is a bined Power over Ethernet (Po E) powered device (PD) interface and currentmode dc/dc controller optimized specifically for isolated converters. The Po E interface supports the IEEE 802.3at standard for a type 1 PD, which is equivalent to the 13W standard of IEEE 802.3-2008.
The TPS23757 supports a number of input voltage ORing options including highest voltage, external adapter preference, and Po E preference.
The TPS23757 has an output flag indicating if an external...
