DATA SHEET AAT2749 3.0MHz Step-Down Converter and Low-VIN LDO General Description The AAT2749 is a two channel power regulator that operates from 2.3V to 5.5V. The AAT2749 contains a 3.0MHz, 600mA step-down converter and a low input voltage 300mA LDO regulator. The step-down converter can deliver 600mA of load current. The 3.0MHz switching frequency minimizes the size of external components while keeping switching losses low. The AAT2749 step-down converter maintains high efficiency throughout the operating range, which is critical for portable applications. Fixed frequency, low noise operation can be forced by a logic signal on the MODE pin. The AAT2749 also contains a 300mA LDO regulator with input voltage capability as low as 1.62V.
