MP6302

The MP6302 is an energy storage and release controller. It charges storage capacitor from input during normal operation. Once the storage capacitor is charged to the selected voltage, the charge is stopped, and the storage capacitor is separated from the input. The charging circuit maintains the storage voltage after the charge is completed. The MP6302 keeps monitoring the input voltage, and releases the charge from storage capacitor to the input capacitor when the input voltage is lower than a selected release voltage. It regulates the input voltage close to release voltage for as long as possible. The MP6302 has built-in current limit circuit during the charging of the storage capacitor. The storage and release voltage can be programmed to user desired value by external resistors. MP6302 comes in a tiny 2mmx3mm QFN10 package and requires a minimum number of readily available standard external components.
