Tanii-san,
PMP9013 uses the TPS23752 and features sleep mode in a self-driven flyback topology
TPS23752EVM-145 uses the TPS23752 and features sleep mode and VFO mode in driven flyback topology
TPS23751EVM-104 uses the TPS23751 and features VFO mode…
Hello na na78 and thank you for your interest in PoE solutions from TI.
When starting a PoE design, I suggest reviewing our TI Designs at a system level (not starting with an IC search and focus). The best way to do this is to go www.ti.com/.../refdesignsearchresults…
Taher,
The TPS23751 is a PoE PD controller with integrated PWM controller. For aux applications, I recommend reading the Advanced ORing app note in the TPS23751's technical documents section of its product page.
I also recommend looking at PMP8812…
Part Number: TPS23754 Other Parts Discussed in Thread: , TPS23752 Hello,
I would like to ask You for help with our design including TPS23754. This design is following TPS23754EVM-383 EVM, but to be on a safe side I include our schematic (please ignore…
Yes, there will be a few other items to change. I'd recommend looking at the PMP8812 TI reference design ( http://www.ti.com/tool/PMP8812?keyMatch=pmp8812&tisearch=Search-EN#Technical Documents ) which converts the TPS23752EVM-145 (5V, 5A) to a 12V, 2…
Joe, TPS23751 (based on TPS23751EVM-104) may be a better choice/fit for a TPS23753 based design. TPS23751 supports the simpler flyback type of configurations operating at type 2 power levels. The TPS23751EVM delivers 5V at 4.5A and features a "green mode…
Hello Gim.
There are several PoE PD devices in the TI portfolio which support up to 25.5W (Class 4) power. These include the TPS23785B, TPS23751, TPS23752, TPS23754, TPS23756, and TPS2378. They can extend their reach up to 30W with an optional boost…
TPS23756 can support the 12V adapter from the primary side. You can refer to the TPS23756EVM ( http://www.ti.com/lit/pdf/slvu329 ) which can support 5V/5A output from 10.5V - 57V at the primary side input.

Part Number: TPS23751 Other Parts Discussed in Thread: TPS23752 Hello,
I would like to design a PoE PD with the following specifications using TPS23751.
・Vin(min) 36V ・Vin(max) 57V ・Vout(Nom) 24V ・Iout(max) 1.25A ・Class 4 ・Output Power…
Other Parts Discussed in Thread: TPS2375 , TPS23752EVM-145 , TPS23752 how is MPS (maintain power signature) implemented in POE designs?
the spec says to have a 10mA load at a certain interval - which how it is done with Class 0 or 1
I do not see how…
