1MHz Step-Down Converter General Description The AAT1123 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 AAT1123 the ideal choice for portable applications. The AAT1123 is available in either a fixed version with internal feedback or a programmable version with external feedback resistors. It can deliver up to 600mA of load current while maintaining a low 25µA no load quiescent current. The 1MHz switching frequency minimizes the size of external components while keeping switching losses low.
