Hi,
I am making a bike powered USB charger. The output must be 5V@2.1A. Considering that the wheel won't have a constant speed, what is the best way of regulating the output voltage? As I know that a linear voltage regulator will make much more losses of energy in heat, I wanted to use a buck-boost (step up/down) converter, but every tutorial I found on internet for similar projects were using a linear voltage regulator.
What should I use?
Thanks.
