Simple Circuit Charges Lead-Acid Batteries
Abstract: A flyback converter implements a current-limited power supply to charge lead-acid batteries. The MAX668 PPM controller
limits the output current, and the flyback transformer provides isolation and flexibility for input voltages both above and below the
battery voltage. The MAX4375 current-sense amplifier monitors the charging current and uses its internal comparator that below a
designed threshold the flyback convert
