TINA/Spice/LM5166: STEP Input simulation.

Part Number: LM5166
Other Parts Discussed in Thread: TINA-TI

Tool/software: TINA-TI or Spice Models

Hi ,

I am using LM5166X for one of my design. We are using COT mode. 

V in = 24 V , V out = 5 V , I out = 210 mA, Soft start delay = 7 mS. . I have simulated this and got results. At nominal constant 24V it is OK. 

1. How I can set STEP input. Initially  24V is set. then let us say after 10 mS ,  it drops to 7V for 1 mSec and again restores to 24V . I would like to see results for such input i.e voltage dip and hold time check. 

2. How can I see efficiency graphs or waveform after simulation?

I have attached my .TSC file for reference. 

webench_design_4082167_74 - Copy.tsc

Pl. revert.
