Description
General part information
LT8686S Series
The LT8686S 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 LT8686S combines two 42V capable 2A buck regulators with two 8V capable 2A buck regulators. The two 42V regulators may be combined to provide up to 4A of output current using a single inductor. Similarly, the two 8V regulators may be combined to provide up to 4A 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 LT8686S 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 LT8686S incorporates thermal shutdown and individual channel cycle-by-cycle current limit for short-circuit protection and robust operation.APPLICATIONSAutomotive SystemsIndustrial Controls and Power Supplies
