UCC28C44: What the difference between Pspice model 'UCC28C44_START' and 'UCC28C44_STEADY' ?

Mia Ma

Part Number: UCC28C44

Hi team,

Here is a confusing thing that want to confirm with you, why there is two model of UCC28C44？

What the difference between 'START' version and 'STEADY' version? Or if anything we need to pay attention during the simulation in terms of these two version?

Thanks a lot.

Hi Mia,

The steady model has initial conditions applied intended to speed up the simulation through the start-up phase. The start model will not have the same initial conditions applied and this allows the simulation to more accurately represent how the IC behaves as circuits are initially biased during start-up. The start model will take longer to reach steady state compared to the steady model. Thanks for connecting through E2E.

Regards,
