TPS61170: Speed Up LTSpice Simulation

Abigail Leonardi

Part Number: TPS61170

Tool/software:

Hi,

I have a customer who is currently using LTSpice and experiencing a significant slow-down in runtime of their simulation due to the TPS61170 LTSpice part. This is confirmed as when the TPS61170 is removed from the circuit, the simulation runs as expected.

Does the team have any recommendations here to attempt to speed up the runtime? It would help with the new product development. Thanks!

    Hi Abigail,

    Please help check whether there is very small ESR, for example, 1mΩ, used in series with the input and output capacitors? If yes, please try to delete the ESR or make them bigger(try > 5mΩ).

    Regards
