Product Details

Demonstration circuit 2552A is a dual-output, high efficiency, high density, µModule regulator with 4.5V to 16V input range. Each output can supply 25A maximum load current. The demo board has a LTM4678 µModule regulator, which is a dual 25A or single 50A step-down regulator with digital power system management. Please see LTM4678 data sheet for more detailed information.

DC2552A powers up to default settings and produce 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 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.
