Manufacturer Skyworks


Description :

The AAT1154 SwitchReg™ is a member of AnalogicTech's Total Power Management™ 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 the -40ºC to +85ºC temperature range.
