    EVALUATION KIT AVAILABLE Click here for production status of specific part numbers. MAX20098 General Description The MAX20098 is an automotive 2.2MHz synchronous
    step-down controller IC with 3.5µA IQ. This IC operates
    with an input-voltage supply from 3.5V to 42V and can
    operate in dropout condition by running at 99% (typ) duty
    cycle. It is intended for applications with mid-to highpower requirements that operate at a wide input voltage
    range such as during automotive cold-crank or engine
    stop-start conditions.
    The step-down controller operates at up to 2.2MHz frequency to allow small external components, reduced
    output ripple, and to guarantee no AM band interference.
    The switching frequency is resistor adjustable (220kHz
    to 2.2MHz). FSYNC input programmability enables three
    frequency modes for optimized performance: forced fixedfrequency operation, skip mode with ultra-low quiescent
    current, and synchronization to an external clock. The IC
    also provides a SYNC output to enable two controllers to
    operate in parallel. The IC has a factory-programmable
    spread-spectrum option for frequency modulation to minimize EMI interference.
    The PGOOD output indicates when the voltage is within
    regulation range. Protection features include cycle-bycycle current limit and thermal shutdown. The MAX20098
    is specified for operation over the -40°C to +125°C automotive temperature range. Applications ●● Infotainment Systems
