Other Parts Discussed in Thread: LM5155, , PMP22800
Tool/software:
Hi,
I've trying to run a simulation using the LM5155 model in Pspice and I'm having trouble getting the correct output.
The simulation is trying to get 24V out from 12V input.
Earlier I had issues with getting the gate output from the LM51551 model, and even now the peak voltage on the gate output is incorrect (<6V).
I've tried using different opto-isolator models, mosfets, output diode, using separate grounds, using the same ground but I can't seem to solve the issue.
The simulation design I'm trying to run is based on the PMP22800 reference design by TI.
Before trying to simulate the PMP22800 design, I was able to successfully simulate the boost reference design for this chip.
I'm attaching screenshots as well as the simulation file.
Any help with this will be appreciated.
Thanks,
