The AAT1155 SwitchRegTM is a member of AnalogicTech's Total Power Management ICTM (TPMICTM) product family. The step-down switching converter is 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.
