Part Number: LMR54406 Other Parts Discussed in Thread: TPS560430 Tool/software: Hi team，
1. How is the upper and lower tolerance of the adjustable output voltage regulation of the LMR54406 chip determined? Does it include the error of the FB…
Part Number: LMR54406 Tool/software: Hi there, i have a set of ten prototypes with the LMR54406 mounted. It is used to generate a 5V from 24V.
Problem is: three of the ten prototypes are not working correctly. There is no voltage regulation and input…
Part Number: LMR54406 Tool/software: Hi all,
I'm for sure making a missunderstandment of the datasheet, cause after carefully crunching some numbers using the formulas in the datasheet the inductor value result for my use case (max output current 0…
Part Number: LMR54406 Tool/software: Hi,
Are there any documents or information comparing the waveforms of the LMR54406's FPWM and PFM modes?
I am concerned about how much larger the voltage ripple will be when using the PFM method at light loads…
Part Number: LMR54406 Tool/software: Hi team,
I cannot change individual component values when using Webench Power Designer.
For example, if Rfbt and Rfbb is changed from the original value, both resistor values reset to the original value when Cout is…
Hi Jimmy,
As I not heard from you in some time, I will close this thread. Should you need more assistance, please feel free to re-open the thread with the requested relevant information.
Thank you,
