GENERAL DESCRIPTION
No external inductor is required for operation. 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 AME7730 contains a thermal management circuit to protect the device under continuous output short circuit conditions. The AME7730 is available in SOT-26 / TSOT-26 package and is rated from -40OC to 85OC. 100mA Regulated Charge Pump n Functional Block Diagram VIN φ2 CC+ φ1 φ1 φ2 VOUT φ1 φ2 EA EN Control GND n FEATURES
