PRODUCT DATASHEET AAT1141 SwitchRegTM General Description The AAT1141 SwitchReg is a 1.4MHz step-down converter with an input voltage range of 2.7V to 5.5V and output voltage as low as 0.6V. It is optimized to react quickly to a load variation. The AAT1141 is available in fixed voltage versions with internal feedback and a programmable version with external feedback resistors. It can deliver 600mA of load current while maintaining a low 35μA no load quiescent www.DataSheet4U.com current. The 1.4MHz switching frequency minimizes the size of external components while keeping switching losses low. The AAT1141 is designed to maintain high efficiency throughout the operating range, which is critical for portable applications.
