Other Parts Discussed in Thread: LM5145
Hi. I want to use TPS40170 in the LTSpice. But I downloaded from TPS40170 TINA-TI Transient Spice Model. But I didnt simulate. The TPS40170 don't operate. There is no load.

Hi Samet,
Try running the model on TINA. It's not intended for LTspice. We also have the PSPICE for TI design and simulation tool.
And you can use the TPS40170 quickstart calculator available here to assist with component selection: https://www.ti.com/product/TPS40170#design-development##design-tools-simulation.

Hi,
Thank you for supoorting. I must do the FFT result to eliminate the conducted emission for switching frequency. I can do in the LTSpice. I want to see FFT results besides functional verification. Can I do this in the TI design ?
Thank you,
Best Regards.

Hi Samet,
Should be possible, although it's difficult to model the quasi-peak detector of the EMI receiver to get an accurate prediction.
See the LM5145 datasheet for more detail on input filter design (this is the next gen part to the TPS40170).

Tim
