At the LTM4641’s core is a 10A step-down regulator accepting an input voltage between 4.5V to 38V delivering a regulated output voltage adjustable between 0.6V and 6V with 1.5% total accuracy. As many as four LTM4641s can be paralleled to deliver up to 40A of output current. A current limit foldback in case of an overcurrent condition is included as a basic protection feature. Operation is guaranteed for industrial & military temperature grades supporting -55°C to 125°C operation.
