Product Details

Demonstration circuit 2672A-A is a complete non-isolated 48V input, dual-output, high efficiency, high density µModule regulator with 30V to 58V input range. Each output can supply 25A maximum load current. The demo board has a LTM4664 µModule regulator, which is a dual 25A or single 50A step-down regulator with digital power system management. Please see the LTM4664 datasheet for more detailed information.

DC2672A-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.
