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
