Part Number: PMP20588 I am using PMP20588 reference design. It is working fine. I want to use this DC-DC converter section for 54VDC, 2.5A output . Is it possible with this device? If yes,please suggest me the required changes in the present schematic…
Hi Mortiz,
Customer referred a similar reference design PMP20588 and the transformer Pri: Sec is 1:5.
The transformer customer used Pri:Sec PL3254-001SR_SPEC_A.pdf is also 1:5(not 1:1).
Could you please review again what might be wrong?
Thanks,
Allan

Hello,
We would recommend one of our single port PSE designs, but they use a newer part.
The TIDA-00465 uses a 54V DC input and an LDO to get the 3.3V rail.

TPS23861 is support four ports, can suport two ports? how to design it? is there reference design, thanks.
Hi Gareth,
Thank you for your questions.
On the PSE side, we don't have a single port only PSE but the TPS23861 is recommended for single port up to 30W PSE applications. You can find a reference design PMP20588 where the TPS23861 is used in a single…
