Fast Transient 800mA Step-Down Converter General Description The AAT1110 SwitchReg™ is a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product family. It is a 1.4MHz stepdown 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 AAT1110 the ideal choice for portable applications. The AAT1110 is available in either a fixed version with internal feedback or a programmable version with external feedback resistors. It can deliver up to 800mA of load current while maintaining a low 27µA no load quiescent current. The 1.4MHz switching frequency minimizes the size of external components while keeping switching losses low.
