Overview

Product Details

Demonstration Circuit 2007A-A features a PolyPhase® design using the LTM4630EV, the high efficiency, high density, dual 18A, switch mode step-down power μModule® regulator. The input voltage is from 4.5V to 15V. The output voltage is jumper selectable from 0.9V to 1.8V. The DC2007A-A can deliver a nominal 70A output current. As explained in the data sheet, output current derating is necessary for certain VIN, VOUT, and thermal conditions. The LTM4630 on the DC2007A-A always operates in continuous conduction mode. The switching frequency can be programmed through a resistor or can be synchronized to an external clock signal. The board allows the user to program how its output voltage ramps up and down through the TRACK pin.
