Overview
PRODUCT DATASHEET AAT1140 SwitchRegTM General Description The AAT1140 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 AAT1140 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.
