LMR23630-Q1: Can I get simulation result?

Hi Chase:

you can use Pspice to simulate the behavior of LMR23630, it can support long time simulation like 5ms, and you can zoom the SW. 

but normally, small ratio of failure phenomena can't reproduce by simulation.

Do you know what is the issue?

thanks

Dear Daniel,

Thank you for your support.

They had a failure issue from customer, so they want to compare the waveform between failure device and ideal situation.

anyway I downloaded Pspice simulation file from LMR23630 product page and changed some values to make 7V output.

but I cannot simulate it. something is wrong, but I cannot find it. Could you help me to simulate? (I used Steady_State schematic.)

HI

Let me check and reply to you later

Hi 

pls see below result ,  I download the pspice model from LMR23630 product folder, and set the same parameters. 

Thanks

Hi

last simulation is use FPWM Versin DRR, below is DDA result

Dear Daniel,

Thank you for your support.

Could you share the file which you simulated? then I can test it with different parameters.

Best regards,

Chase

Hi 

pls try this

Dear Daniel,

Thank you for your support.

I checked error message when I open the dsn or opj file.

Could you help me? I am using Pspice for TI 2020.

Best regards,

Chase

Dear Daniel,

Thank you for your support. My customer still checks the simulation file. I will post another thread if I have more question.

Best regards,

Chase
