Another application for this circuit is as a "linear current booster" (LCB). Common LCB uses include running motors and other devices directly from a solar panel with no battery. In the LCB mode of operation, it is possible to use the circuit to change a low current solar panel input to a higher current (but lower voltage) output. When the circuit is used as an LCB, the current rating of the solar panel should be sufficient to power the load through the regulator. A 12V 1 amp rated solar panel (about 10 watts) would be a good match for this circuit, panels with lower current ratings can also be used, depending on the output current requirements.

The purpose of a voltage regulator circuit is to take a variable input voltage and produce a steady output voltage. Two common regulator types are linear and switch-mode. Linear regulators are simple, but waste a lot of power in the process of regulating the voltage. Linear regulators can be thought of as self adjusting series resistors. Switch-mode regulators such as this one are much more efficient. Switch-mode regulators convert DC input voltages to pulses of high voltage DC. The DC pulses are used to charge a storage capacitor to the desired output voltage. The voltage is regulated by varying the width of the DC pulse. This circuit is suitable for a variety of uses. If you have a solar powered 12 Volt lead-acid battery power source, the circuit can be used to efficiently power lower voltage devices. It can be used to provide power to devices that normally use a set of small batteries for power. Common voltages such as 1.5V, 3V, 4.5V, 6V, 7.5V, and 9V can be produced by this circuit. The circuit has been used to power small fans, portable radios, a miniature TV, and more.
