Hi,

I am using LM25117QPSQE in constant current mode and I need to plot the stability graph in this mode. The calculator excel sheet tool in for constant voltage and so I cannot use it for my application because the values that this sheet uses if considering constant voltage and so I am getting incorrect/irrelevant values for some components.

Kindly share the calculator for constant current mode.

Regards,

Jignesh C. Patel

    Hello Jignesh,

    Unfortunately the existing calculator cannot model frequency response in CC mode. We do not have a calculator for such a configuration.

    If you like you can email me your specification and component values you have selected and I can simulate them for you?

    I will provide you with my email and you can contact me there. I will close this thread in the mean time.

    Hope this helps?
