DESCRIPTION

The LT?8685S is a highly flexible, four channel, current

mode, monolithic regulator able to power a wide range

of automotive and industrial applications while occupying

minimal board space.

The LT8685S combines two 42V capable 2.5A buck regulators

with two 8V capable 4A buck regulators. The two

42V regulators may be combined to provide up to 5A of

output current using a single inductor. Similarly, the two

8V regulators may be combined to provide up to 8A of

output current using a single inductor. Individual channel

enable, track/soft-start and power good pins provide flexible

power supply sequencing and control. The LT8685S

features a Silent Switcher 2 architecture, plus selectable

spread spectrum mode, to provide ultralow EMI/EMC

emissions while delivering high efficiency at high switching

frequencies.

The LT8685S incorporates thermal shutdown and individual

channel cycle-by-cycle current limit for short circuit

protection and robust operation.
