DC1759A

LTM4620A DC to DC Converter and Switching Regulator Chip 3.2505VDC to 3.3495VDC/4.925VDC to 5.075VDC Output Demonstration Circuit

The demonstration circuit 1759A features the LTM®4620AEV, the high efficiency, high density, dual 13A, switch mode step-down power module regulator. 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.
