Tool/software:
Hi Team,
I am investigating the TPSM63610 and am trying to simulate the Inverting Buck-Boost capabilities of the part through the example circuit shown in section 8.2.2 of the datasheet. However, the outputs of the simulation do not match what I am expecting to see. Could you verify whether the PSPICE model is capable of supporting an IBB configuration for the TPSM63610. And if so, could you verify that the circuit I have below is correct?
Thank you,
Filipe
Hello Filipe,
IBB designs usually cannot be directly simulated with a typical pspice model unless it is a dedicated IBB model. Since this device does not have a dedicated IBB model, you can simulate using the method shown in Section 4.4.3 of the following application note: https://www.ti.com/lit/an/snva856b/snva856b.pdf
Make sure to set up your measurement probes with the proper reference point in order to see the correct voltages.
Best regards,
Ridge
Hello,
TPSM63610_TRANS_edited_for_ibb.zip
Please use the attached file. I edited the steady state page, but you can follow the example for the startup page as well. Please note for proper measurements, use the differential probes to reference everything to the Vout pin (which is the GND in IBB) of the device.
Here is a screenshot to show what I mean:
