TINA/Spice/LMZ14203: LMZ14203 TINA-TI Convergence Problem

Part Number: LMZ14203
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

Dear All,

         I downloaded the LMZ14203EXT Unencrypted PSpice Transient Model for TINA-TI simulation and I get a convergence error . Why I would get a convergence error? Thanks in advance.LMZ14203_Sim.TSC

  • Hello,

    We wave looked into the issue and made the following changes to make it work.

    1. Adjusted the analysis parameters properly.

    2. Provided a step input voltage (0V -->28V) instead of DC.

    3. Added IC=0 to output & SS capacitor.

    PFA the updated test schematic 1184.LMZ14203_Sim.TSC.

    Below is the simulation result.

    Thanks & Regards,

    Arpan Gupta
