RAA271041 Features

* ▪ ASIL-D Functional Safety ▪ 40V boost and buck integrated driver controller ▪ FET drivers support source/sink current of 2A/3A ▪ Low IQ with ECM mode of 8µA typical (buck Channel 1 only) ▪ Separate or Combined Wake (Enable) inputs for each channel ▪ Minimized FET ON and OFF times (25ns and 45ns) ▪

RAA271041 General Description

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.
