General Description

The AAT1150 SwitchReg? is a member of AnalogicTechs Total Power Management IC? (TPMIC?) product family. The step-down switching converter is ideal for applications where high efficiency, small size, and low ripple are critical. Able to deliver 1A with internal power MOSFETs, the current-mode controlled IC provides high efficiency using synchronous rectification. Fully internally 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 temperature range.
