AAT1154IAS-2.5-T1 datasheet

General Description
The AAT1154 SwitchReg(TM) is a member of AnalogicTech(TM)'s Total
Power Management(TM) IC
product family. The Step-down switching converter is ideal for
applications where high efficiency, small size, and low ripple are
critical. Able to deliver 3A with an internal power MOSFET, the
current-mode controlled IC provides high efficiency. Fully internally
compensated, the AAT1154 simplifies system design and lowers external
part count. The AAT1154 is available in an SOP-8 package,
rated over -40 to 85°C.
