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 mosfets…
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
Part Number: PMP8878 Hi Sir,
As per BOM of PMP8878 the Inductor L2 (N87 cores) and Transformer T2 (3C97 cores) core material details are available.
1. Could you please share the RM core (TDK/ Ferroxcube) Part number used in the design.
2. These cores…
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…
Hello again Sherman,
A half-bridge controller, like the LM5036, can be used in full-bridge topology if two half-bridge gate drivers are used. Here is one (older) example using the UCC27201: https://www.ti.com/tool/PMP8878
The entire line of half-bridge…
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 SLUA6…
Part Number: UCC25230 Other Parts Discussed in Thread: PMP8878 Hi TI engineers,
I use UCC25230 as an auxiliary power source.Output 9V.Using LPD5030 as coupling inductor for second side power supply.But the oscillation is serious.The original edge is not…
