DC2164A-A, Demonstration Circuit 2164A-A features a PolyPhase design using two paralleled LTM4630EY-1 high efficiency, high density, dual 18A, switch mode step-down power module regulator. The input voltage is from 4.5V to 15V. The output voltage is jumper selectable and can be set to 0.9V, 1.0V, 1.2V, 1.5V or 1.8V. DC2164A-A can deliver nominal 70A output current. Output current derating is necessary for certain VIN, VOUT and thermal conditions. The LTM4630-1A on DC2164A-A always operate 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
