[QUOTE="steelPHASE, post: 469728, member: 13488"] Yes I would also add a coil in the output as well. They aren't too noisy but I would err on the side of over engineering in this situation. As for switching - I haven't tested that. It would probably need some damping resistor across the switches so that it never goes open circuit as it switches between values. If there is a large cap on the output, it would probably absorb most spike issues. Turn on spikes are not something I have noticed in experimental circuits but I haven't really looked for them. Again a large cap would probably damp issues. [b][i]Note: There are different versions of these modules. Some step up, some step down. Choose what is needed but the methodology needed in this application will be the same.[/i][/b] - step down version : [url]https://www.ebay.com.au/itm/5-PCS-DC-Adjustable-Buck-Converter-Step-Down-Power-Supply-Module-LM2596-GL/283108308772[/url] [/QUOTE]
