Product Summary
The TPS23753APW is a combined Power over Ethernet (PoE) powered device (PD) interface and current-mode dc/dc controller optimized specifically for isolated converter designs. The PoE 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 IEEE 802.3af). The TPS23753APW supports a number of input-voltage ORing options including highest voltage, external adapter preference, and PoE preference. The applications of the TPS23753APW include IEEE 802.3at Compliant Powered Devices, VoIP Telephones, Access Points, Security Cameras.
