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 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 crit...
