DescriptionThe TPS23753Aisa 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 standardasa 13-W, type PD. The requirements for an IEEE 802.3at type1
device area supersetof IEEE 802.3-2008 (originally
IEEE 802.3af).
The TPS23753A supportsa numberof input-voltage
ORing options including highest voltage, external
adapter preference, and PoE preference.
The PoE interface features an external detection
signature pin that can also be usedto disable the
internal hotswap MOSFET. This allows the PoE
function to be turned off. Classification can be
programmedto anyof the defined types witha single
resistor.
The DC-DC controller featuresa bootstrap start-up
mechanism with an internal, switched current source.
This provides the advantagesof cycling overload fault
protection without the constant power lossofa pullup
resistor.
The programmable oscillator may be synchronizedto higher-frequency external timing reference. The
TPS23753A features improvements for uninterrupted
device operation throughan ESD event.
