General Description
The AAT3110 ChargePump™ is a MicroPower
switched-capacitor voltage converter that delivers
a regulated output. No external inductor is required
for operation. Using three small capacitors, the
AAT3110 can deliver up to 150mA to the voltage
regulated output. The AAT3110 features very low
quiescent current 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
AAT3110 operates in an output-regulated voltage
doubling mode. The regulator uses a pulse-skip-
ping technique to provide a regulated output from a
varying input supply. The AAT3110 contains a ther-
mal management circuit to protect the device
under continuous output short circuit conditions.
The AAT3110 is available in a surface mount 6-pin
SOT23 or 8-pin SC70JW package and is rated
from -40 to 85°C.
The AAT3110 ChargePump™ is a member of
AnalogicTech's Total Power Management IC prod-
uct family.
