DC2007A-A

LTM4630 Demo Board | 70A Polyphase Step-Down (2x LTM4630), 4.5V ≤ VIN ≤ 15V, VOUT = 0.9V to 1.8V @ 70A

产品详情

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.

产品详情

Demonstration circuit 1892A features the LTM4630EV, the 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 programmable from 0.6V to 1.8V. DC1892A can deliver up to 18A maximum in each channel. As explained in the LTM4630 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. For high efficiency at low load currents, the MODE jumper (JP1) selects pulse-skipping mode for noise-sensitive applications or Burst Mode® operation in less noise-sensitive applications.
