Overview
AME, Inc.
AME7720 / 7721 n General Description 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 combiwww.

com nation 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.
The AME7720 / 7721 is available in SOT-25 / SOT-26 package and is rated from -40OC to 85OC.
