Hi Team,

Do we have simulation models of TPS40077?

Thanks in advance

I do not see one linked on-line, so I will have to look.

I am still looking for a stand alone model for the TPS40077, but it is supported in PSpice for TI, and you can request access from the TPS40077 product folder, under Design and Development tools

I was not able to find a model for the TPS40077, but I was able to find a model for the TPS40075, which uses the same modulator core and oscillator programming, but adds external synchronization and remote sense capabilities, so they could use that model for simulation.

Hi Peter,

Thanks for support please see feedback below.

Peter James Miller said in his message that the structure of the TPS40075 IC is close to TPS40077 and can be used in simulations. When I searched among the models of TI ICs in Cadence, I could not see the TPS40075 IC. You can see from the picture below. There is TPS40055 listed in the picture below, did he mean it…

There is actually an Excel file for stability analysis of the TPS40077 on TI's website. For now this file works for me. It doesn't necessarily have to be a PSPice model. My aim was to see the effect of the resistor connected to the KFF pin while drawing the closed loop Bode curves of dc/dc. This Excel file works for me.

Thanks in advance
