Demonstration circuit 2081A-A features the LTM4630EV, the high efficiency, high density, dual 18A, switch mode step-down μModule® regulator. The input voltage is from 4.5V to 15V. The output voltage is programmable from 0.6V to 1.8V. DC2081A-A is configured as dual-phase, single-output, which can deliver up to 36A maximum. The board designs with minimum components to demonstrate this high efficiency, high density μModule. As explained in the data sheet, output current de-rating is necessary for certain VIN, VOUT, and thermal conditions.
