Mini DC-DC Voltage Stabilizer/Regulator Module

  Ran across this and just wanted to share. Great for getting all the different voltages of your components to operate off of

one source. One module per each different voltage requirement, small and light weight. Adjustable for input voltage and output voltage and only $3.80 US

The critical question is: how clean is the output?

It is my understanding that radio performance can take quite a hit as a result of a noisy regulator.

 Your right. Grounding and shielding is SOP for components such as this. As for how clean the output is visit the site , conduct your own tests, and add capacitors as needed. At $3.80 US it is a very useful component. The site has other regulators as well, enjoy exploring.

I came across this site some time ago: prodctodc.com Interesting stuff, but lot of it can be found cheaper.  

Comment by Geoffrey Preston on September 11, 2013 at 9:43am

prodctodc.com seems to have some good stuff. Too bad we cant get the things we need in the USA at a decent price.

You can also try this one that handles both step and and step down (useful if you want 12V from a 3S and can't manage the voltage drop as the battery goes down.) I use one for my video, after going through an LC filter, and it seems O.K. for noise.

 I like the screw terminals and mounting holes on that one, it could be swapped out easily. What LC filter are you using?

I ordered a couple and an extra to blow up :). Ill hook it up to the oscilloscope to test it's worthiness. Ill post the results here in probably a month when it decides to arrive from china.

is bad DC-DC converter. when DCin/DCout is more than 2 and amperage 1-1.5A he very hot! After 30seconds i cant touch he more than 2-3 secons. I've heard that kis-3r33s is much better!

Very noisy bastard.. But nothing a filter can't handle.

If you'll be pushing these modules to their limits (above 3 amps), don't forget two things - a good heatsink (those tiny radiators with a sticky tape) and some 1000uf low esr capavitors on the input and output. Otherwise, they'll fail soon enough...
