Hello,

I need to select an output capacitor for a switch-mode power supply and
don't have an idea about a maximum acceptable ESR for the capacitor. As I
found out, the ESR can be calculated from the formula of tan delta and is
directly proportional with it. What would be a good value for such a
capacitor, considering that the inductance value for the SMPS is 10uH, the
current load is 2.5A maximum and the frequency is around 250kHz ?

Thank you !

Lucian
