I have created a design for the TPS40140 using SwitcherPro 3.17.

Two phase single output converter model.

VinMin:
10.8V VinMax: 13.2V Vout: 1.2V Iout: 32A 

I would like to use MOSFET IRFH7914 at high-side and 2 no.s of IRFH7932 at low-side, but the switcherpro is not letting me to use 2 IRFH7932 at low side,

and secondly when i select high side/low side mosfet then automatically the other one i.e. low side /high side mosfet is also becoming the same part. Please help me how to proceed.

Thanks & Regards,

Pradeep.

    Hi Pradeep,

    Using your inputs in both the online and desktop v3.17 of SwitcherPro, I was unable to reproduce your problem. Infact, SwitcherPro fails to create this design.

    Can you please let me know if the inputs entered were different or modified using 'Edit inputs' option?

     

    Regards,

     

    Amod
