Abstract:This circuit includes a battery charger (MAX712) and step-down switching regulator (MAX5089) for handling the power
portion of the charger. By controlling the regulator the MAX712 acts as a battery-charge controller, producing outputs of 7V to
16V. It operates from any DC source capable of delivering the desired fast-charge current, with this condition: the output voltage
must equal 1.7V multiplied by the sum of (two plus the number of batteries to be charged in series).
