Part Number: PMP41158 Hi Team,
We are facing an issue related to PMP41158 and would like your support to understand and resolve it.
As per the schematic available on the website, we have mounted only one section of IC U1. In this setup, we have mounted…
Part Number: PMP41158 Hi Team,
I am using the LM5137FBQRHARQ1 IC in our design. The input voltage range is 6.5V to 36V, and the expected output is 4.5V at up to 40A.
We are currently facing an issue with the output voltage under load. When we check…

I have several questions regarding the current feedback layout of the LM5137F-Q1-EVM12V :
It seems that the demo board intentionally routes the current feedback…

Using dual LM5137F-Q1-EVM12V modules to implement a 4-Phase synchronous buck converter. During load testing, significant oscillation was observed in both the output…
Hi Yuming,
It's always difficult to connect two boards like this and achieve perfect current sharing. Make sure to run COMP-to-AGND as a diff pair between each board, as this sets the current command for the secondary controller. Use one compensation…
Two phases is possible with the LM5146 voltage-mode controller, but it's an outer current loop and thus not accurate per-phase sharing like a conventional current-mode controller.
If 80V max Vin is adequate, take a look at the LM5137 2-phase EVM setup…
