dc-dc converters

Post by ed » Mon Jun 29, 2020 12:03 pm

I've recently been playing with LM2596 converters as an alternative to 7805 and 7809 regs.
they are cheap as chips on ebay on the small packaged boards.
so far so good and the benefit of minimum losses when dropping lots of volts seems a good plus point.

however I'm having a senior moment and I can't quite work out how to get rid of a 5mv spike at precisely 52.36 khz on a 5v output with no load.
I don't think it's going to affect anything in use, it's just irking me.
There's nowhere you can be that isn't where you're meant to be
