Hello,
I would like to know the Fsw calculation formula for the MPQ4317.
The datasheet only has a table of Fsw values based on recommended resistor values
Hello, welcome back to the MPS forums!
While the datasheet for this IC doesn’t have a specific formula, please refer to the following graphs that map Rfreq to the actual switching frequency. This is detailed on page 15 of the MPQ4317 datasheet.
Best,
Krishan
Could you please share the calculation formula that only MPS FAEs know, instead of just the datasheet?
It feels awkward to select the Fsw (switching frequency) based solely on the graphs
I can ask the PLs on my end and get back to you with a specific formula that was used to graph the following images that are shown in the datasheet. I do agree that would be more intuitive than the graphs provided.
I’ll get back to you on this thread when they provide these details.
Best,
Krishan
