Product Number: LTC3722-1
Software Version: LTSpice 26.0.1
We are currently attempting to simulate Frequency Response Analysis (FRA) for the LTC3722-1 using LTspice. However, we are unable to obtain the Bode plot waveforms in the respective window, even when using the example applications available in the LTspice library.
We have also followed the instructions provided in the LTspice help documentation, but the issue persists.
Could you please assist us in resolving this? Your guidance would be greatly appreciated.
Thank you for your support, and we look forward to your response.8865.CH-1 Design PSFB design fra .asc
