The AME7720 / 7721 is switched-capactitor voltage doublers that delivers a regulated output. No external inductor is required for operation. Using three small capacitors, the AME7720 / 7721 can deliver up to 60mA to the voltage regulated output. The AME7720 / 7721 features very low output pipple and high efficiency over a large portion of its load range making this device ideal for battery-powered applications. Furthermore, the combination of few external components and small package size keeps the total converter board area to a minimum in space restricted applications. The AME7720 / 7721 contains a thermal management circuit to protect the device under continuous output short circuit conditions.
