Hi Abhilash
TPS62933 can support 12V,3A if you use lower fsw like 500kHz, the Tj will be 112℃ under 30℃ Ta according to the Webench simulation Tool: https://webench.ti.com/power-designer/switching-regulator/customize/217?VinMin=24&VinMax=24&O1V=12&O1I=3&base_pn…
Hi
1.The test SW is tested using a ground ring, which is consistent.
2.Your SW test also has -2.9V, and the SW in TPS56837 below does not exceed -1V, which obviously exceeds the requirement, doesn't it? Or does the current SW exceeding requirements not…
Hi Sean
It's nice to see Cin and RFB_bottom are close to device. (Cin can be even closer if place on the same layer with TPS56837)
The RFB_top should also place close to device other than Vo. The FB1 trace is long and is susceptible to noise. You…
Part Number: LMR50410 Other Parts Discussed in Thread: TPS56837 Hello team,
Can we measure Soft start time of LMR50410 as same as TPS56837?
I read the below document, but it requires SS pin...

Hi Ali,
I'm the AE supporting TPS56837.
Thanks for evaluating TPS56837. If you don't need PGood signal, sure you don't need the external pull-up 5V. You can just float PG-pin.
Hello Zhang,
We have a new part TPS56A37 could support your application. TPS56A37 is p2p with released TPS56837 (28V 8A), just support higher Iout range (28V 10A).
You can evaluate TPS56837 first.
TPS56A37 will be RTMed in 1Q24.
Hello Gareth,
I will review TPS56637 and Ryan will review TPS548A28 circuit.
About TPS56637 design,
1. The input cap C619/C620 voltage rating is 10V, not suitable for 12V input. Please use higher voltage rating caps.
2. Suggest to use our recommended LC…

My apologies about that, I thought the part I was looking at had auto-skip light load efficiency, but it appears I was mistake.
Looking through our other 6A and 8A converters with light load efficiency, I think the TPS56837 offers the highest…
