Abstract:This design idea shows how a switching converter regulates its input voltage and enables solar cells to charge batteries
at optimum rates. The DC-DC step-down regulator, MAX639, and solar cells minimize battery charging time by regulating and
maintaining solar battery voltage at a level necessary for maximum power transfer.
A battery of solar cells can charge a battery of NiCd cells with better than 80% efficiency, provided the solar battery voltage
exceeds the fully charged NiCd output by one diode drop. For that ca……
