AAT1143 Datasheet | Advanced Analogic Technologies

1MHz 400mA Step-Down Converter General Description The AAT1143 SwitchReg™ is a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product family. It is a 1MHz 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 AAT1143 the ideal choice for portable applications. The AAT1143 is available in either a fixed version with internal feedback or a programmable version with external feedback resistors. It can deliver 400mA of load current while maintaining a low 25µA no load quiescent current. The 1MHz switching frequency minimizes the size of external ponents while...
