n AEC-Q100 Qualified for Automotive Applications The LT®3508 is a dual current mode PWM step-down
DC/DC converter with internal power switches capable
of generating two 1.4A outputs. The wide input voltage
range of 3.7V to 36V makes the LT3508 suitable for regulating power from a wide variety of sources, including
automotive batteries, 24V industrial supplies and unregulated wall adapters. Both converters are synchronized
to a single oscillator programmable up to 2.5MHz and
run with opposite phases, reducing input ripple current. …
