DC3190B-F

DC3190B-F is a demonstration circuit 3190B-F 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 PSM. 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 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.
