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.
- AEC-Q100 qualified, Grade 1: -40°C to +125°C
- Supports ASIL C Systems
- VIN operating range from 4.0V to 42V
- VOUT = 5.0V or 3.3V (factory programmable)
- High-efficiency synchronous buck regulator with efficiency up to:
- 95%; VIN = 12V; VOUT = 5V; F = 440kHz
- 92%; VIN = 12V; VOUT = 5V; F = 2.2MHz
- 2% VOUT accuracy over temperature, load, line
- Factory programmable soft-start
- Soft-stop output discharge during disable
- RSTb output which doubles as Monitor fault or Buck Fault Indicator
- Fixed switching frequency: 2.2MHz or 440kHz
- Spread Spectrum Modulation (SSM), pseudo-random frequency and dwell time
- Enable/disable
