GENERAL DESCRIPTION
The AAT2146 SwitchReg is a 2MHz 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 AAT2146 incorporates a unique low noise architecture which reduces ripple and spectral noise. The AAT2146 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 37μA no load quiescent current. The 2MHz switching frequency minimizes the size of external components while keeping switching losses low.
