DC/DC 3.5-30V to 4.0-30V Booster Converter Step Up Voltage Regulator LM2587
I am very impressed with this product. I was using this thing to raise the voltage from 12V to 20V, and I have to say, no matter what voltage I put between 12V and 18V, the voltage stayed at 20V and it wouldn't fluctuate by more than .2V at most. I'm only using about 1-2amps at most. I wouldn't know how this would work with higher current applications since I didn't test it beyond that. That being said, I did notice the unit wouldn't get hot at all, so, it could definitely handle more than what I was using
