Overview
High Efficiency, Low Noise, Fast Transient 400mA Step-Down Converter General Description
The AAT1147 SwitchReg is a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product family.
It is a fixed frequency 1.
4MHz step-down converter with an input voltage range of 2.
7V to 5.
5V and output voltage as low as 0.
6V.
The AAT1147 is optimized for low noise portable applications, reacts quickly to load variations, and reaches peak efficiency at heavy load.
The AAT1147 output voltage is programmable with external feedback resistors.
It can deliver 400mA of load current while maintaining high power efficiency.
The 1.
4MHz switching frequency minimizes the size of external components while kee...
