Product Description: TPS23753APWR

The TPS23753APWR is a combined Power over Ethernet (PoE) Powered Device (PD) interface and current mode DC-DC controller designed specifically for isolated converters. The PoE implementation supports the IEEE 802.3at standard as a 13-W Type 1 PD. IEEE 802.3at Type 1 requires devices to be a superset of IEEE 802.3-2008 (originally IEEE 802.3af).

The TPS23753APWR supports multiple input voltage ORing options including maximum voltage, external adapter preference and PoE preference. The PoE interface has an external detection function signature pin, which can also be used to disable the internal hot-swap MOSFET. This allows the PoE function to be turned off. Classification can be programmed to any defined type of resistor with a single program. The DC-DC controller has a bootstrap start mechanism with an internal switched current source. This provides the advantage of cyclic overload fault protection without the constant power loss of pull-up resistors. The programmable oscillator can be synchronized to a higher frequency external timing reference. The TPS23753APWR features non-stop improvements to device operation through ESD events.
