TPS2640: Inductive sources and loads

Greg
Expert 2031 points
Part Number: TPS2640

Hello,

If a buck converter drives an eFuse, is the buck converter considered an inductive source if the eFuse breaks the current suddenly?
If an eFuse drives a buck converter, is that considered an inductive load?

Thanks and regards,

Greg

    Hi Greg,

    The answer is NO for both cases. 

    The buck converter does Voltage to current to voltage conversion. The inductor element acts as current source but again converted into voltage source by the output capacitance of buck converter.

    Let us know if you are facing any challenges in using eFuse 

    Best regards

    Hi Rakesh,

    Thank you for the helpful answer.  I guess I better not skimp on the capacitance ;-).  I'm asking questions up front so that I won't have any challenges.  I want to make sure I have all of the protection devices where they will be needed.

    Best regards,

    Greg
