Product Details

Demonstration circuit 3190B-F is a high current, high density, high efficiency open-frame μModule® regulator with 45V to 65V input range. The DC3190B-F demo board has a LTP8802A-1B module regulator that provides the microprocessor a 3.3V voltage from 54V power distribution architecture with digital power system management (PSM). The maximum output current for the DC3190B-F demo board is 140A. See the LTP8802A-1B data sheet for more detailed information.

The DC3190B-F 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 DC3190B-F, download the graphical user interface (GUI) software LTpowerPlay^® onto your PC and use Analog Devices 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.
