Product Details

Demonstration circuit 3190A-A is a high current, high density, high efficiency open-frame μModule^® regulator with 45V to 65V input range. The demo board has a LTP8800-1A μModule regulator which provides microprocessor 0.75V voltage from 54V power distribution architecture with digital power system management. The maximum output current for the demo board is 150A. Please see LTP8800-1A data sheet for more detailed information.

DC3190A-A 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 part, 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 and store the configuration in EEPROM, view telemetry of voltage, current, temperature and fault status.
