Demonstration circuit 2830A features the LTM4636EY, a 40A high efficiency, switch mode step-down µModule® regulator which is controlled by the LTC7106EDDB, a precision, bidirectional, 7-Bit current DAC with PMBus interface. The LTC7106 is used to adjust the output voltage of the LTM4636 by way of the PMBus. The LTM4636’s input voltage range is from 4.7V to 15V and the output voltage range is from 0.6V to 3.3V. De-rating is necessary for certain VIN, VOUT, frequency and thermal conditions. The LTC7106 requires an input voltage from 2.5V to 5.5V and on DC2830A it’s powered directly from the DC1613A dongle. The LTC7106 provides three ranges of IDAC output current: Nominal Range (–64µA to 63µA), Range High (–256µA to 252µA) and Range Low (–16µA to 15.75µA). The nominal range is optimized with the highest accuracy. It is recommended that users design the resistor divider using the nominal range of the IDAC setting.

To explore the power system management features of the LTC7106, download the GUI software LTpowerPlay® onto your PC and use ADI’s I2C/SMBus/PMBus Dongle DC1613A to connect to the board. LTpowerPlay allows the user to reconfigure the part on-the-fly, view IDAC current value and fault status.

The LTM4636 and LTC7106 data sheets must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC2830A.
