LV Boost LVBoost is a tiny voltage boost converter that can take voltages as low as 0.5V and convert them into higher, more useful voltages like 3.3V or 5V. It has an exceptionally low quiescent draw - typically under .4mA. these features make LVBoost a great choice for powering projects from solar or other renewable energy sources. From a 3V input, 500mA @5V out is easily achievable, allowing you to charge nearly any portable device that meets the USB spec. The output voltage is set with a small screw potentiometer on the side of the LVBoost.
