General Description

The AAT1155 SwitchReg is a step-down switching converter ideal for applications where high efficiency, small size, and low ripple are critical. Able to deliver 2.5A with an internal power MOSFET, the current-mode controlled IC provides high efficiency. Fully internally compensated, the AAT1155 simplifies system design and lowers external parts count.

The AAT1155 is available in a Pb-free MSOP-8 package and is rated over the -40°C to +85°C temperature range.
