Part Number: LM5148 Tool/software: Hello,
I implement LM5148 buck for two power supplies: +24V to +5V and +24V to +15V on same board, and on sequence +5V, then +15V. They both have +5V connected to VCCX.
Unfortunately, the +15V keeps failing. It does…

Hello Christian,
You can use a single LM5148 for 12A output current.
please see evaluation board linked below.

Part Number: LM5148 Tool/software: Hello, I was wondering if I use the LM5148 as it is to drive GAN transistor with max Vgs of 5.5V. In case if it is possible what should I be carefull of? I was thinking about creating a 2.2MHz buck converter from 48V…
Part Number: LM5148 Tool/software: Hi,
We are using LM5148 for a buck converter application. Input 45V, Output 12V, 10A
At current above 5A, the duty of the converter seems to become unstable while the output continue to stable. We are using external…
Hi Tom,
Theoretically, this should work (however, let me confirm this internally with the designers of this reference design).
Thanks,

Hi TI's engineers，
We use TI's buck controller LM5148 and we want to configure it as 15A Output current, but no matter how we change R176 and C267, they are all under 8A~9A current limiting protection…

Part Number: LM5143 Other Parts Discussed in Thread: LM5148 , LM5190 Tool/software: hi sir
I Can't find the key word" CC or constant current " in the data sheet of LM5143 & LM5148
if the two parts support the function
need spec as b…
