Hi there!
I found this reference design that almost does what I'm looking for.

The reference design takes an audio signal and feeds it through op amps to manipulate the FB pin.
I tried simulating this design in PSPICE, but instead of having the audio signal portion, I removed it and just added a 200mV voltage source.
According to the reference design, a 200mV input to the tracking circuit should give me a boost output of 14V. Unfortunately I am not getting the same result (see attached PSPICE schematic and also waveform output).
I'm not very familiar with simulation tools, so maybe I'm doing something wrong? Could you help take a look at my simulation or provide a working one that matches the reference design?
I'm hoping to be able to match the PSPICE simulation with the reference design results, so I can then start to modify the simulation design for my use case.
