Part Number: PMP8878 Hi team,
How can designing an input Filter for the PMP8878 module? If you have any CM DM inductor and Y cap X cap calculation. Please share them with me.
Part Number: PMP8878 Hi,
My customer is referring PMP8878 and has questions about "C2" as below;
1. How should we design the rated current of C2?
2. How should we design the capacitance of C2?
3. How should we design the rated voltage of C2? …
Part Number: PMP8878 Other Parts Discussed in Thread: UCC25230 , UCC27324 Dear TI Experts,
The bias supply(12VS) in PMP8878 is designed for 12V/0.2A using UCC25230. How TI arrived at 0.2A?.
What is the driving current required for the synchronous…
Part Number: PMP8878 Hi Sir,
Could you please suggest any TI document which explains the the PCB thickness, layers or design details of the planar used in PMP8878.
Thanks and Regards,
Nesh
Hi Sir,
I was searching for the part No or details of the RM core used in PMP8878.
The details which was shared in the reply seems to Payton planar transformers

Part Number: UCC28250 Other Parts Discussed in Thread: PMP8878 Dear all,
How the switching frequency of PMP8878 is decided as 200KHz?. what are the parameters which limits the switching frequency?. What will happen if we the switching frequency doubled…
Part Number: UCC28250 Other Parts Discussed in Thread: PMP8878 , UCC25230 , , PMP8877 , UCD3138 Hello sir,
We are planning to develop a Brick module taking PMP8878 as a reference. But we have the requirement of Input over voltage and under voltage protection…
Hi David,
Thanks for connecting through E2E. Here is one PMP8878 reference design I found that uses UCC28250 in a DC/DC telecom module. UCC28250 is the predecessor to UCC28251. They are functionally the same and the differences are explained in SLUA673A…
Hi David,
switch node at 15V input.
switch node at 30V input.
switch node at 40V input.
The electrolytic capacitor can not be connected in parallel, because this is the 1/4 brick module power source without enough space.
This input filter…
Part Number: UCC25230 Hi Ti Engineers,
This is the schematic.It uses UCC25230 as auxiliary power conversion chip converting from 36V-72V to 9V .The problem is that the T2 second side oscillation is serious as below channel 3.
The schematic diagram…
