AAT1157 | 1MHz 1.2A Step-Down DC/DC Converter

The AAT1157 SwitchReg is a member of AnalogicTech's Total Power Management IC (TPMIC) product family. The Step-down switching converter is ideal for applications where fixed frequency and low ripple are required over the full range of load conditions. The 2.7V to 5.5V input voltage range makes the AAT1157 ideal for single cell lithium-ion/polymer battery applications. Capable of up to 1.2A 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. The device operates at a fixed 1MHz switching frequency across all load conditions. The AAT1157 is available in the Pb-free, 16-pin 3x3mm QFN package and is rated over the -40C to +85C temperature range.
