AAT1120中文资料500mA Step-Down Converter数据手册Skyworks规格书

描述 Description

The AAT1120 SwitchReg is a 1.5MHz 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 AAT1120 the ideal choice for portable applications.
The AAT1120 delivers up to 500mA of load current, while maintaining a low 30µA no load quiescent current. The 1.5MHz switching frequency minimizes the size of external components, while keeping switching losses low. The AAT1120 feedback and control delivers excellent load regulation and transient response with a small output inductor and capacitor.
The AAT1120 is available in a Pb-free, 8-pin, 2x2mm STDFN package and is rated over the -40°C to +85°C temperature range.
