MAX20098

Versatile Automotive 36V 2.2MHz

Buck Controller with 3.5µA I

General Description

The MAX20098 is an automotive 2.2MHz synchronous

step-down controller IC with 3.5µA I

. 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 high-

power 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 fre-

quency 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 fixed-

frequency 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 mini-

mize EMI interference.

The PGOOD output indicates when the voltage is within

regulation range. Protection features include cycle-by-

cycle current limit and thermal shutdown. The MAX20098

is specified for operation over the -40°C to +125°C auto-

motive temperature range.
