MAX20419 Automotive PMIC for ADAS Applications

Analog Devices Inc. MAX20419 Automotive PMIC for ADAS Applications is a high-efficiency, 3-output, low-voltage DC-DC converter IC. The OUT1 boosts the input supply to 5V at up to 750mA. Two synchronous step-down converters operate from a 3.0V to 5.5V input voltage range and provide a 0.8V to 3.8V output voltage range at up to 3.6A. The boost converter achieves ±1.9%, and the buck converters achieve ±1.4% output error over load, line, and temperature range. The IC features a 2.2MHz fixed-frequency pulse-width modulation (PWM) mode for better noise immunity and load-transient response and a pulse-frequency-modulation mode (skip) for increased efficiency during light-load operation. The 2.2MHz frequency operation allows the use of all-ceramic capacitors and minimizes external components. Programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions. Integrated low R_DS(ON) switches improve efficiency at heavy loads and make the layout a much simpler task for discrete solutions. Other features include soft-start and overcurrent / overtemperature protection. The Analog Devices MAX20419 also has several redundancies and diagnostic features for compatibility with ASIL-rated applications.
