Description

span id="lblDescription">

The AAT1140 SwitchReg is a 2.0MHz step-down converter with an input voltage range of 2.7V to 5.5V and output voltage as low as 0.6V. It is optimized to react quickly to a load variation.

The AAT1140 is available in fixed voltage versions with internal feedback and a programmable version with external feedback resistors. It can deliver 600mA of load current while maintaining a low 35µA no load quiescent current. The 2.0MHz switching frequency minimizes the size of external components while keeping switching losses low.

The AAT1140 is designed to maintain high efficiency throughout the operating range, which is critical for portable applications.

The AAT1140 is available in a Pb-free SOT23-5 package and is rated over the -40C to +85C temperature range.
