Part Number: LM5022 Hi TI,
I'm looking for the PMP2ßß58 schematics, but I can't find it anymore.
Seems to be swiped from net.
Could you help me with that?
Thanks in advance.
Best regards
Alex
Part Number: LM5022 Other Parts Discussed in Thread: PMP20588 I have copied the PMP20058 POE reference design to my circuit board with all the same parts including the Coilcraft transformer. My Vin is 12V and I expect 54V output. My design does not work…
Part Number: PMP20058 The design matches all my specs except for the transformer size. I need to reduce the size of the transformer. The design gives an option between 2 transformers however both the options are too tall. Do you have any recommendation…

The PMP20058 Reference Design is an isolated flyback regulator intended to provide 54V for Power-over-Ethernet (PoE) applications.
IEEE 802.3af (PoE) indicates that the maximum ripple voltage to be:

Hi,
Customer spec is as below, which parameter they need to change and design the transformer?
Vin: 16v~23v
Vout: 54v~57v
iout=1.5A
Part Number: PMP20058 Dear TI,
After check with PMP20058 , the VIN is from 8V to 18V for input voltage.
The LM5022 has accepted the max 60V input voltage.
How can we do to change the input voltage from max 18V to 20.9V(19V+-10%)?
Thank you so much…

I am using the PMP20058 PoE Isolated Flyback Reference Design with the LM5022 to convert 12V to 54V. I have two PCB designs with the same circuit, though not with the same layout. At high current draw, one of the two PCB designs generates…
Hi Alex,
I am the designer of PMP20058. I personally modified PMP20058 to 54Vout @ 1.9A (100W) only at 12Vin, at 8V or 9Vin, peak primary curent is much higher than 12Vin, the primary FETs are sustaining a lot loss, and thermal is an issue. If you refer…
