AM-7  -  Series DataSheet
AME7739  -  Step-Up / Step-Down 60mA Regulated Charge Pump  -  AME, Inc  -  DC-DC Charge Pumps

n General Description
The AME7739 is a charge pump voltage converter that delivers a regulated output. No external inductor is required for operation. Using three small capacitors, the AME7739 can deliver up to 60mA to the voltage regulated output. The AME7739 features very low output ripple 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 keep the total converter board area to a minimum in space restricted applications.
The AME7739 contains a thermal management circuit to protect the device under continuous output short circuit conditions.
The AME7739 is available in SOT-26 package and is rated from -40OC to +85OC.
