Based on the high efficiency topology of switched-capacitor, the Charge Pump Converter is used to halve bus voltage, or halve 2S battery voltage to power system load. It features high efficiency, high integration and high power density. Some Charge Pump Converter products integrates charger function, which supports charging battery directly by halving bus voltage. Some Charger Pump Converter products integrates boost function which can be used with buck charger to charge 2S battery for the benefits of saving BOM cost.
