Hi,

Why does Startup and Steady State exist for TINA-TI Reference Design of UCC 3814 and other AC / DC cotrolars?

Thanks

    Hi,

    Normally we apply Load ,Line transient and do other tests (like current limit) once a device reach it's steady state.

    As Startup simulation takes ~5-10 minutes to reach steady state, we try to provide a separate steady state simulation test bench where you can see device's steady state behavior quickly(~ 2minutes).

    Below are the simulation results for UCC3813-4 Startup and Steady State test benches.

    Startup:

    Steady:

    Dear Mr.Saket,

    Thanks for your information.

    I understand that it is separating types for shortening of time.

    In addition, thank you for the simulation results.

    Regards,
