Output Capacitors on TOPSwitch-JX

2 posts / 0 new

Dears,

I am creating a project on PI Expert Online and have a doubt.

The PI Expert suggested me 6 capacitors of 330uF/50V on the secondary (figure).
Can I use only one of 2200uF/50V? Or 2 of 1000uF/50V?

Thanks a lot,
Paulo

Dear Paulo,

As long as the ripple current rating and ESR of the capacitors are ok for your application, having an equivalent number of uF at the given voltage rating should be ok. Also, in some cases, where there is a need for component redundancy to be more robust against failures, multiple components are preferred. Finally, there may be space restrictions that cause one capacitor configuration to be preferred over another.
