Part Number: PMP20878 Hi Ti Team,
In my design, I have both poe and usb-c as a power source. I want to take the PMP20878 as a reference for POE side. PMP20878 output voltage is 24v. It would be nice setting poe output voltage to 20V to match USB voltage…

Hi Team,
May I have your help to provide PMP20878 gerber file?
I cannot find it on the website but just only schematics, test report and BOM list.
Thanks.
Part Number: PMP20878 Other Parts Discussed in Thread: PMP21318 Dear team,
I am looking for PoE 12Vout/24Vout, and found we have PMP20878 and PMP21318.
We would like to use the same transformer in both two different output design.

May I know is that…
Part Number: PMP20878 Other Parts Discussed in Thread: UCC2897A , TPS2373-4EVM-758 , TPS2373 Dear all,
are the test results for the PMP20878 only valid for an auxiliary supply (40-57 VDC on J3) or was the board tested with a POE supply (IEEE 802.3bt) as…
Part Number: PMP20878 Hello,
Capacitors C27, C100, C102 are all rated at 250V. Is there a reasoning behind this large rating? Would 100V suffice?
Thank you Tim

Thanksgiving.
Part Number: PMP20878 Other Parts Discussed in Thread: TLV431 , TL431 Dear TI Team
I design the PoE-24V Output near as Design "PMP20878" but it doesn't work (I geht only 12V pulses). I Change the Referent resistor (R64) from the TLV431 from…
Part Number: PMP20878 Other Parts Discussed in Thread: TPS2373 , TPS2372 Hello,
Can you provide me with some information on the expected ripple current across C28? Ripple voltage expected of C103? And would U2 be able to utilize the PoE VDD voltage for…
Part Number: PMP20878 Other Parts Discussed in Thread: UCC2897A Just touched the power field,In the schematic diagram, how is transformer T2 and inductance L6 calculated to obtain VCIN of about 12.7v? PMP7410 SCH.pdf
