The RAA271050 is an automotive grade (AEC Q-100 Grade 1, ASIL C) 4A synchronous step-down voltage regulator with integrated high-side and low-side MOSFETs. The output voltage of this buck regulator is fixed to either 5.0V/3.3V. With an input voltage range of 4.5V to 42V, it provides a high-efficiency solution for a variety of point-of-load applications. The RAA271050 works as a primary regulator and companion product with the RAA271000 system PMIC, whose target application is the R-Car V3H processor, where a high-performance complete power solution is required.
