Part Number: PMP22301 Other Parts Discussed in Thread: TPS23754 , , TPS23751 , UCC28630 , UCC28740 Greetings,
With a thought to integrate Power over Ethernet with a SBC with Ethernet capability, came across the TPS23754 (PMP22301).
I have 2 questions at…
Hi Kapil,
Thanks for reaching out!
1. VCC needs be > 9V normally to avoid UVLO. In a regular design, VCC is sourced by a transformer AUX winding and you do not need to use a LDO to source it.
2. Yes TPS23731 is good to use here. PMP22806 is a 12V design…
Part Number: PMP22301 Dear Specialists,
My Customer is considering PMP22301 and has a question.
I would be grateful if you could advise.

In PMP22301, 750318587 (Wurth) is described as a transformer（T2).
However, 750318587 does not have a part number…
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 Chase,
Thanks for reaching out!
Sorry that we currently do not have 24V output TPS23751. One way you can do is using the flyback circuit in PMP22301 ( https://www.ti.com/tool/PMP22301) which is using TPS23754. For connections other than flyback converter…
Hi Romi,
Thanks for reaching out!
Sorry that I did not find a dual output with 24V + 3.3V. If the 3.3V needs low current, is it possible to use a 24V to 3.3V LDO?
Besides, PMP22301 ( https://www.ti.com/tool/PMP22301) is a 24V/0.9A flyback reference design…
Hi Ray,
Thanks for reaching out!
The major cause could be the overvoltage of D4 diode which is rated for 60V. When you have 57V input, the voltage at that diode would be more than 57V/Npri*Nsec+24V=81V. It is recommended to use 100 V or 150 V rated diode…
Hi Brian,
Thanks for reaching out.
AN-1430 is LM5071 based 3.3 V flyback converter reference design. You could consider to modify its secondary side circuit to change the output to 24V.
PMP22301 is a 24-V flyback reference design, you may consider to use…
Part Number: TPS23751 Other Parts Discussed in Thread: LM5155 , PMP20220 , PMP11254 , TIDA-00617 , , TPS23754 , TPS23752 , TPS23756 , PMP22301 Tool/software: Hi,
Is there a design calculator (Excel) which can help in the design, like the one you have for LM5155…
Hi Rob,
You can refer the PMP22301's secondary side for the transformer and resistor value selection ( www.ti.com/.../PMP22301) . It is a 24-V 0.9A design, so the secondary sec side diode/FET rating, and the transformer saturation current rating can…
