Part Number: TPS23754 Other Parts Discussed in Thread: TPS23731 Tool/software: Hi TIer,
May I know the TPS23754/6/1 can archive the line undervoltage soft-stop protection by external circuits? please help provide the reference circuit.

Hi Michael,
Thanks for your patience.
Michael Gilge said: My question is, what could be the reason for not having the T2P go low when adapter power is present and the ADP-pin is higher than 1.5V?
Except the faults like over temperature, or transients during…
Part Number: TPS23754 Tool/software: Hello everyone,
Is there any 24V reference design for TPS23754? I want to design a 24V 30W PoE circuit and I am very new in this PoE world.
I've checked one reference design but I think the PoE transformer is now…
Hi Sijo,
This transformer is for flyback only. May I know if you also changed the circuit from forward converter to flyback converter? If so, could you share you updated schematic.
Sijo Augustine said: Flyback can also use, if there is a design having 12V…
Part Number: TPS23754 Other Parts Discussed in Thread: PMP22301 Tool/software: Hi
I am looking for a PoE PD with dual outputs of 24v and 3.3v using the TPS23754. I have not found the right transformer for this. So far the closest option is the JA4372…
Part Number: TPS23754 Other Parts Discussed in Thread: PMP6812 , , PMP22301 , PMP10288 , PMP9563 , Tool/software: Dear TI members,
I read SLUA535A application report and there are many complicated formular to select correct components.
Before I make automatic…
Hi Louis,
TPS23754's RTN current limiting can not be configured.
The inrush current limit is 100 - 180 mA. The fully-on current limit is 850 - 1100 mA. Above this values will trigger foldback protection.
Best regards,
Diang
Part Number: TPS23754 Tool/software: Hi Sir,
may we know how to calculate the power dissipation? about the primary side transformer/ MOSFET/ secondary schottky and IC.
or what kind of relevant data and information can we refer to here?

Part Number: TPS23754 Other Parts Discussed in Thread: PMP22301 Tool/software: Hello,
The POE+ power supply I have designed following the data sheet etc., for the TPS23754, when connected to a POE++ (Injector) supply of about 56V will pulse and seems…
Part Number: TPS23754 Tool/software: Dear TI Engineer,
We plan to use TPS23754 to achieve 25W(12V/2.25A) POE power supply for our new product, but due to the height limitation, we cannot select the TPS23754EMV-383 reference design transformer. The transformer…
