Analog Devices LTM4636-1 | Demoboard DC2448A-D

Description

Demonstration circuit DC2448A-D features a PolyPhase® design using the LTM®4636-1EY, a 40A high efficiency, switch mode step-down power µModule® regulator with overvoltage and overtemperature protection features. The input voltage range is from 9V to 15V. The output voltage range is 0.6V to 3.3V. The DC2448A-D can deliver a nominal 160A output current. DC2448A-D has on-board hot swap circuit that can disconnect input supply and protect the LTM4636-1 and the load under overvoltage and overtemperature conditions. As explained in the data sheet, output current derating is necessary for certain VIN, VOUT and thermal conditions. The board operates in continuous conduction mode in heavy load conditions.
