Product Details

Demonstration circuit DC1663A features the LTM4628EV, the high efficiency, high density, dual 8A output, switch mode step-down power module. The input voltage is from 4.5V to 26.5V. The output voltage is programmable from 0.6V to 5.5V. 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. The DC1663A sets the LTM4628EV default switching frequency to 400kHz; however the frequency is resistor programmable from 250kHz up to 780kHz.
