TPS54917 frequency

Hakan Karlsson
Prodigy 280 points

I would need to change the switchingfrequency to see how efficiency changes.  But today I can only temporary change the frequency to see the gain/phase plots.  Would love to also be able to set the switchingfrequency is the base design to see how efficiency change.   maybe even get 2 plots so I easier can compare.   Many customers today are looking for that last 1% improvment in efficiency by playing with frequency.       Note: This would be valid for all our parts where we can select frequency

    Currently the only way to change switching frequency is through 'Advanced Inputs' options when creating a new design. We are working on a few new features to add into SwitcherPro and one of them is 'Design Options' where the user will e able to change his/her inputs (including switching frquency, vin, vout, iout etc.) for an existing design. This feature will be released around March / April time frame.
