AAT1150

1MHz 1A Step-Down DC/DC Converter General Description The AAT1150 SwitchReg™ is a step-down switching converter 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 a Pb-free MSOP-8 package and is rated over the -40°C to +85°C temperature range.
