AAT2120 - 500mA Low Noise Step-Down Converter

General Description

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.

Key Features

  • VIN Range: 2.7V to 5.5V VOUT Range: 0.6V to VIN Up to 500mA Output Current Up to 96% Efficiency Low Noise Light Load Mode 45μA Typical Quiescent Current 1.8MHz Switching Frequency Soft-Start Control Over-Temperature and Current Limit Protection 100% Duty Cycle Low-Dropout Operation.
