Demonstration circuit 2616A-D features a polyphase design using the LTM4647EY, a 30A high efficiency, switch mode step-down power µModule regulator. The input voltage range is from 6V to 15V. To use DC2616A-D for input voltage range from 4.7V to 6V, connect INTVCC to SVIN (change R22, R42, R55, R68 from OPT to 0Ω), DRVCC to VIN (change R21, R38, R52, R65 from 0Ω to OPT, R2, R39, R53, R66 from OPT to 0Ω). The output voltage range is 0.6V to 1.8V. The DC2616A-D can deliver a nominal 120A output current with four LTM4647 modules in parallel. 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 pulseskipping mode for noise sensitive applications or burst mode operation in less noise sensitive applications. The MODE_PLLIN pin also allows the LTM4647 to synchronize to an external clock signal. The phase shift between two adjacent phases is 90 degrees. DC2616A-D has the option of choosing both internal and external compensation circuit for LTM4647. The LTM4647 data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC2616A-D.

The LTC6820 provides bidirectional SPI communications between two isolated devices through a single twisted-pair connection. Each LTC6820 encodes logic states into signals that are transmitted across an isolation barrier to another LTC6820. The receiving LTC6820 decodes the transmission and drives the slave bus to the appropriate logic states. The isolation barrier can be bridged by a simple pulse transformer to achieve hundreds of volts of isolation.The LTC6820 drives differential signals using matched source and sink currents, eliminating the requirement for a transformer center tap and reducing EMI. Precision window comparators in the receiver detect the differential signals. The drive currents and the comparator thresholds are set by a simple external resistor divider, allowing the system to be optimized for required cable lengths and desired signal-to-noise performance.Applications Industrial Networking Battery Monitoring Systems Remote Sensors
