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 maintain regulation during a battery dropout event such as cold cranking.
- Minimized FET ON and OFF times (25ns and 50ns)
- Optional pseudo-random spread spectrum clocking
- High-efficiency buck exceeding 80% at 10mA
- Buck frequency options 400kHz or 2.2MHz
- Boost frequency options 400kHz or 2.2MHz (2.2MHz requires Buck frequency at 2.2MHz)
- VBATS sense for Boost Enable during Cold Crank
- Boost Bypass mode (for Buck in CCM)
- External synchronization via SYNC pin
- Dual Over-temperature protection monitors
- 6 x 6 mm 36Ld SC-QFN package
- AEC-Q100 grade 1 qualified
- Functional Safety Features
- Built-in Self Test (BIST) at power up
- Recurring Checks: Internal References, PWM clock, System Clock, PGND/AGND connection, Dual Over-Temperature monitor, ECM Exit Delay, VCC supply.
- Independent References and feedback sense paths for Buck and Boost OV/UV detection
- Independent Fault Indicators for Buck and Boost
- Fail-Safe Output, logic high indicates a trusted device state and all safety monitors are active.
