Part Number: PMP22764 Other Parts Discussed in Thread: LM5033 , LM51551 The PMP22764 uses a Transformer from Coilcraft - ZB1368-AL according to the BOM - but I can't find a Datasheet for this. What is the Transformer's Height...?
Also, I am supporting…
Part Number: PMP22764 Hi Team,
I'd like to design an DC/DC Vin=20-28V, Vout=55V(For PoE application), Pin=60W at 20Vin, 100W at 28Vin isolated converter.
After check the reference design experiment eff around 90%. But, our target Eff is 92%.
1. Do…

One of my customer is want the PSE solution for 54V/1.25A output. We have recommended LM51561H initially & designed the isolated power supply. We are able to achieve…
Part Number: PMP22764 Other Parts Discussed in Thread: LM5156 , LM51561 , LM51551 , LM5155 Hi support team,
The parts layout of tidt115 and tidm849 appear to be different. Isn't the characteristic data of tidt115 the data of the layout of tidm849? Is the…
Part Number: PMP22764 Hi team,
My customer is looking for reference design for 8 port PSE isolated power supply.
The spec : Vin: 20v~48v, Vout:55v, Pout:160W
I have found that pmp22764 which is also for PSE isolated power supply. It is pretty fit to…
Hi Tommy,
Thanks for reaching out.
I found the following points:
- You should add a resistor to properly bias TL431.
- A zener diode has to be added to protect TL431, as the abs max. rating will be exceeded otherwise.
You can also refer to this reference…
