Description

The AAT1150 SwitchReg™ is a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product family. The step-down switch- ing converter is ideal for applications where high efficiency, small size, and low ripple are critical. Able to deliver 1Awith internal power MOSFETs, the current-mode controlled IC provides high effi- ciency using synchronous rectification.  Fully inter- nally compensated, the AAT1150 simplifies system design and lowers external parts count. The AAT1150 is available in an MSOP-8 package and is rated over the -40°C to +85°C temperatu range.
