产品详情

Demonstration circuit 3190A-B is a high current, high density, high efficiency open-frame μModule® regulator with 45V to 65V input range. The demo board has a LTP™8800-4A μModule regulator that provides the microprocessor a 0.75V voltage from 54V power distribution architecture with digital power system management. The maximum output current for the demo board is 200A. Refer to the LTP8800-4A data sheet for more detailed information.

The DC3190A-B 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 thepart, download the GUI software LTpowerPlay® onto your PC and use ADI’s I2C/SMBus/PMBus dongle DC1613A to connect to the board. LTpowerPlay allows for reconfiguration of the part on-the-fly and stores the configuration in EEPROM, view telemetry of voltage, current, temperature and fault status.
