The AAT1154 SwitchReg is a member of AnalogicTech 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 -40 to +85C temperature range.
