DC2141A - LTM4647 Demo Board | Buck μModule, 6V ≤ VIN ≤ 15V or 4.7V ≤ VIN ≤ 6V, VOUT = 0.6V to 1.8V @ 30A

Demonstration circuit 2141A features the LTM®4647EY, a 30A high efficiency, switch mode step-down power μModule regulator. The input voltage range is from 6V to 15V. To use DC2141A for input voltage range from 4.7V to 6V, connect INTVCC to SVIN (change R22 from OPT to 0Ω), DRVCC to VIN (change R21 from 0Ω to OPT, R28 from OPT to 0Ω). The output voltage range is 0.6V to 1.8V. Derating is necessary for certain VIN, VOUT, frequency and thermal conditions. The DC2141A offers the TRK/SS pin allowing the user to program output tracking or soft-start period. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE_PLLIN jumper selects pulse-skipping mode for noise sensitive applications or Burst Mode® operation in less noise sensitive applications.
