RAA271041 - Cold Crank Boost and Buck Controller
The RAA271041 is a controller for a dual regulator system capable of supporting ASIL-D automotive systems which must operate during battery dropout conditions.
The Channel 2 boost regulator maintains the voltage rail which supplies the downstream Channel 1 buck regulator, allowing the buck output to
