Overview
Fast Transient 400mA Step-Down Converter General Description The AAT1146 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 voltage as low as 0.
6V.
It is optimized to react quickly to a load variation.
The AAT1146 is available in fixed voltage versions with internal feedback and a programmable version with external feedback resistors.
It can deliver 400mA 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.
The AAT1146 is designed to main...
