AME7730
100mA Regulated Charge Pump
n General Description
The AME7730 is a charge pump voltage doublers that
delivers a regulated output. No external inductor is re-
quired for operation. Using three small capacitors, the
AME7730 can deliver up to 100mA to the voltage regu-
lated output. The AME7730 features very low output ripple
and high efficiency over a large portion of its load range
making this device ideal for battery-powered applications.
www.DaFtuarSthheeermt4oUr.ceo, tmhe combination of few external components
and small package size keeps the total converter board
area to a minimum in space restricted applications.
The AME7730 contains a thermal management circuit
to protect the device under continuous output short cir-
cuit conditions.
The AME7730 is available in SOT-26 / TSOT-26 pack-
age and is rated from -40OC to 85OC.
