Other Parts Discussed in Thread: LM5170
I have a design based on an LM5170-Q1 and am at the stage of working out the outer control loop compensation.
For the inner loop I'm using the transfer function from the data sheet, equation 30. From this I have selected the inner loop compensation values. What I'm now attempting to so is the outer loop but that requires the transfer function from ISET to Vout for both boost and buck modes. I can back it out from the spreadsheet but it would be better if I could find it in some documentation.
I'd like to verify my designs phase margin, I am using a python script to calculate the coefficients. Currently this is based on the values selected by the spreadsheet.
