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.
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).
- High-efficiency buck exceeding 80% at 10mA.
- Buck frequency options 440kHz or 2.2MHz.
- Boost frequency options 440kHz or 2.2MHz
(2.2MHz Boost requires 2.2MHz Buck f.
