How-To: Provide Stable DC Voltage From Higher Voltage Source

How-To: Provide Stable DC Voltage From Higher Voltage Source

Have you ever wanted to add a 5V device to your car, like a single board computer? Most cars run a 12V power system and would cause damage to a 5V device. Or have you wanted to control a device at a stable voltage when the source voltage fluctuates at a higher value? This can happen with solar panels and generators. If so, you want a DC to DC Voltage Converter like the one shown in this video.

@Tracy:

When you say “basically make sure whatever you get is rated twice what you expect to use it for…” do you mean twice the voltage, twice the current, or perhaps something else?

I bought a huge number of these things and did a lot of experimentation with them. Without going into a huge amount of technical detail basically make sure whatever you get is rated twice what you expect to use it for… If you have a noise sensitive project maybe even lower than that. Their efficiency is great, and they work fine but if you need weak signal RF or have other sensitivity issues you may have to add other circuitry to clean it up for such as bypassing etc. We found on our spectrum analyzer almost all of them are very quiet at a quarter to half of their rating with the noise goes up exponentially and across wide bandwidth from there on almost all of them.
