AAT2148 Datasheet | Skyworks Solutions

DATA SHEET Low-Noise, Fast Transient 1A Step-Down Converter General Description The AAT2148 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 AAT2148 incorporates a unique low noise architecture which reduces ripple and spectral noise. The AAT2148 is available in fixed voltage versions with internal feedback and a programmable version with external feedback resistors. It can deliver 1A of load current while maintaining a low 37μA no load quiescent current. The 2MHz switching frequency minimizes the size of external ponents while keeping switching losses...
