TPSM41625: PSpice Simulation

Kendra Nelson
Prodigy 10 points

Part Number: TPSM41625

I would like to use PSpice to simulate the load transients on this device. The pre-configured model works great, however when I add extra capacitance and alter a few of the external resistors to match our design specifications, the program will not work anymore. Is this a simulation issue? Or am I missing some information?

Design specifications:

- VIN = 12 V, VOUT = 0.85 V, Switching frequency = 400 kHz, Soft Start = 2 mS

Thanks
