This Low Dropout Voltage (LDO) solar charge controller uses a simple differential amplifier and series P channel MOSFET linear regulator –their compatibility seems like a marriage made in heaven.

This is a simple solar boost converter and voltage limiter circuit that charges a 12V battery from a 6V solar panel. It also demonstrates MPPT (Maximum Power Point Tracking) capability. When we think ...

While many people don’t tend to think about it, solar power is one of the easiest and most reliable ways to maintain vehicle batteries without needing to plug into an outlet, and a good solar trickle ...
