Power Converter For 3.3V

Hello All,

I have found an inexpensive buck converter to get my 12 volts down to 3.3 to drive lasers or LEDs. They are DC To DC Converter Buck Step-down Module LED Power 3A 12V To 5V 3.3V

I found them on Ebay and got 10 of them for around $14.00 including shipping.

Linky I hope this link works!

They are what to look for. I'm sure searching a product code would bring up suppliers in your country. I have posted a small schematic for a 6v regulated supply using one somewhere, I'll see if I can find it shortly.
