Hi team,
My customer is evaluating with LM5122, and they are reference the PMP21274 design
However the inductor is too big, can you please help them simulate…

Hello,
due to some issues with LM5122 I have investigated some reference designs. In PMP21274 there is an assembly option for Q5 and R9. What is the purpose of this option…
Part Number: PMP21274 Hi,
Base on TI PMP21274 reference design schematic, we build PCBA to testing thermal but find out have high Temp issue (~90 degree for Inductor).
But rework MODE pin to GND then got normal temp for inductor (~45 degree).
May…
Part Number: LM5122 Other Parts Discussed in Thread: PMP21274 Tool/software: Hello, I am trying to create a design for a boost converter using the LM5122 with the following requirements: Vin nom = 12, 10V<Vin<50; Iout nom =2.2A, 100mA<Iout<2.5A.
Power…
Hi Joao,
Thanks for using the e2e forum. Unfortunately, I cannot open kicad_pcb files. However, based on the pictures you attached, I already got an overview of the layout.
Here are my comments: Schematic: - No input caps are used. This is highly…
Hello Youhao Xi,
You have suggested a design for 48V, 2.5A DC-DC boost converter in my original post.

I have a little bit confused about capacitors which are set in BOM,
C2,C3,C4,C5,C6,C7,C8, These all capacitors…
Hi User,
I think Dave was asking if your design required an isolated or non isolated power supply.
If looking for a non-isolated design, our latest reference design looking at the TI Design library is PMP21274.
If looking for an isolated design…
So, if you could (eventually) find some LM5122 controllers you could replicate this reference design from TI. The following link shows test results, schematics, BOM, layout files, gerbers, etc.

This is a synchronous…
