Product Details

The DC3190B-E is a high current, high density, high efficiency open-frame μModule^® regulator with 45V to 65V input range. The DC3190B-E evaluation board has an LTP^®8800-2 μModule (micromodule) regulator which provides microprocessor 0.75V voltage from 54V power distribution architecture with digital power system management (PSM). The maximum output current for the evaluation board is 135A. See LTP8800-2 data sheet for more detailed information.

The DC3190B-E 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-to-dc converter. To fully explore the extensive PSM features of the DC3190B-E, download LTpowerPlay^® graphical user interface (GUI) software to your PC and use Analog Devices I²C/SMBus/PMBus dongle DC1613A to connect to the evaluation board. The 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.
