Product Details

Demonstration circuit 2863A features the LTM®4680, which is a dual 30A or single 60A μModule® regulator with a 4.5V to 16V input range. Two LTM4680 μModule ICs are paralleled on this board to deliver 120A maximum load current. The output voltage is adjustable from 0.5V to 3.3V. Refer to the LTM4680 data sheet for more detailed information.

The DC2863A powers up to default settings and produces power based on configuration resistors without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter. To fully explore the extensive power system management features of the LTM4680, download the GUI software LTpowerPlay® onto your PC and use ADI I2C/SMBus/PMBus dongle DC1613A to connect to the board. LTpowerPlay allows the user to reconfigure the part on-the-fly and store the configuration in EEPROM, view telemetry of voltage, current, temperature and fault status.

GUI Download

The software can be downloaded from LTpowerPlay.
