LM5157-Q1: The worst case analysis of pspice simulation model

Josh Wei

Part Number: LM5157-Q1

I want to know which simulation model of LM5157-Q1 support worst case analysis. If the flyback works at the worst condition, will the model reflect the real accuracy of voltage, especially the output?

Thanks!

    Hi Josh,

    Thanks for using the e2e forum.
    The LM5157x-Q1 Transient model is for simulating in time domain, including load transients and steady-state operation.
    This is the model you are looking for.
    The Average Model is for stability simulation and bode plot analysis.

    On the testbench within the model is a disclaimer that lists all the features that are not simulated.
    For example, there is no simulation of temperature or overtemperature protection.
    Other features like overcurrent protection, UVLO etc. are simulated.

    Best regards,
    Niklas
