GENERAL DESCRIPTION
No external inductor is required for operation. 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. φ1 φ2 VOUT φ1 φ2 Control EA + EN GND n FEATURES
