Description

span id="lblDescription">

The AAT2120 SwitchReg is a 1.8MHz step-down converter with an input voltage range of 2.7V to 5.5V and output as low as 0.6V. Its low supply current, small size, and high switching frequency make the AAT2120 the ideal choice for portable applications.

The AAT2120 delivers up to 500mA of load current, while maintaining a low 45A no load quiescent current. The 1.8MHz switching frequency minimizes the size of external components, while keeping switching losses low. The AAT2120 feedback and control delivers excellent load regulation and transient response with a small output inductor and capacitor.

The AAT2120 maintains high efficiency throughout the load range. The AAT2120 unique architecture produces reduced ripple and spectral noise. Over-temperature and short-circuit protection safeguard the AAT2120 and system components from damage.

The AAT2120 is available in a Pb-free, 8-pin, 2x2mm STDFN package and is rated over the 40C to +85C temperature range.
