DC3082A-C Demo Circuit for LTM4681

Analog Devices Inc. DC3082A-C Demo Circuit for LTM4681, a PolyPhase® single output DC/DC step-down μModule® regulator. The LTM4681 comes with digital power system management. DC3082A-C is configured as a 16-phase single output using 4× LTM4681. The factory default input voltage is 12V typical, and the output voltage is 1V at 480A typical or 500A peak with recommended 400LFM forced airflow. The demo board output voltages can be adjusted from 0.6V to 1V. Programming the output voltages to any value greater than 1V requires derating output current based on thermal derating curves provided in the datasheet of the LTM4681. The heat sink or other appropriate electronic cooling systems can also be used with forced airflow to optimize the output power further when the output is on and loaded with maximum output current.
