Hi guys,

Thanks for the inputs, but the original question is not getting answered. How are you coming up with these values? Other than what other people have used in the past, are the values just trial and error using an oscilloscope and changing out the different values, or is there a formula?

Does this have to be done AFTER I build my circuit, or if I follow this setup, I can use it on all of my different setups? Here's an example from another company for their product:



Can I use this, or is it specific to their circuit? This is what they're using to power their circuit which is an amplifier. Mine is just to supply power to my pics and transistors controlling relays.

Thanks,
Tony
