AAT2146W
Low-Noise, Fast Transient 600mA Step-Down Converter
General Description
The AAT2146W SwitchReg is a 2MHz fixed frequency 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 AAT2146W is ideal for applications where fixed frequency and low ripple
voltage are required over the full range of load conditions.
The AAT2146W is programmable with external feedback resistors.
It can deliver 600mA of load current while maintaining a low 150μA no-load quiescent current.
The 2MHz switching frequency minimizes the size of external components while keeping switching losses low.
