Demonstration circuit 2616A-A features a polyphase design using the LTM4645EY, a 25A high efficiency, switch mode step-down power µModule regulator. The input voltage range is from 6V to 15V. To use DC2616A-A for input voltage range from 4.7V to 6V, connect INTVCC to SVIN (change R22, R42 from OPT to 0Ω), DRVCC to VIN (change R21, R38 from 0Ω to OPT, R2, R39 from OPT to 0Ω). The output voltage range is 0.6V to 1.8V. The DC2616A-A can deliver a nominal 50A output current. As explained in the 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_PLLIN jumper selects pulse-skipping mode for noise sensitive applications or burst mode operation in less noise sensitive applications. The MODE_PLLIN pin also allows the LTM4645 to synchronize to an external clock signal. The phase shift between the two phases is 180 degrees. DC2616A-A has the option of choosing both internal and external compensation circuit for LTM4645. The LTM4645 data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC2616A-A.
