850kHz 700mA Synchronous Buck DC/DC Converter General Description The AAT1151 SwitchReg™ is a step-down switching converter ideal for applications where high efficiency is required over the full range of output load conditions. The 2.7V to 5.5V input voltage range makes the AAT1151 ideal for single-cell lithiumion/polymer battery applications. Capable of more than 700mA with internal MOSFETs, the currentmode controlled IC provides high efficiency using synchronous rectification. Fully integrated compensation simplifies system design and lowers external parts count. The device operates at a fixed 850kHz switching frequency and enters Pulse Frequency Modulation (PFM) mode for light load current to maintain high efficiency across all load conditions. The AAT1151 is available in Pb-free MSOP-8 and QFN33-16 packages and is rated over the -40°C to +85°C temperature range.
