Low Voltage Compact Boost Converter
This cute little boost converter utilizes Pulse Frequency Modulation based on the 2108A regulator to provide a starting voltage as low as 0.7v, and a consistent regulated output of 5 or 3.3 volts DC. It's compact size (11x11mm board layout, with a total component thickness of 7.7mm) permits easy integration into any size of project!
The wide input range of these allows them to be used with a plethora of different power sources:
- Solar arrays with as few as two cells
- Single cell batteries of almost any chemistry
- Alkaline batteries that are already too exhausted to work in most consumer devices
- Small DC motors being used as wind turbines
