ANALOG DEVICES DC2378A-A

DC2378A-A demonstration circuit features the LTM®4650EY, the high efficiency, high density, dual 25A, single 50A, 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. Two outputs can be connected in parallel for a single 50A output solution with optional jumper resistors. The board allows the user to program how its output ramps up and down through the TRACK/SS pin. The output can be set up to either coincidentally or ratiometrically track with another supply’s output. Remote output voltage sensing is available for improved output voltage regulation at the load point. These features and the LTM4650EY in a compact 15mm x 15mm x 5.01mm BGA package make it ideal for use in many high density point-of-load regulation applications.
