AME7720 / 7721
n General Description
The AME7720 / 7721 is switched-capactitor voltage
doublers that delivers a regulated output. No external in-
ductor is required for operation. Using three small ca-
pacitors, the AME7720 / 7721 can deliver up to 60mA to
the voltage regulated output. The AME7720 / 7721 fea-
tures 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 combi-
www.nDaatitoanShoefetfe4Uw.ceoxmternal 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.
