The AAT1156 SwitchRegTM is a member of AnalogicTechTM's Total Power Management ICTM (TPMICTM) product family. The step-down switching converter is ideal for applications where high efficiency is required over the full range of load conditions. The 2.7V to 5.5V input voltage range makes the AAT1156 ideal for single-cell lithium-ion/polymer battery applications. Capable of more than 700mA with internal MOSFETs, the current-mode controlled IC provides high efficiency over a wide operating range. Fully integrated compensation simplifies system design and lowers external parts count.
