Product Details

Demonstration circuit 2798A is a high voltage, dual-phase single output boost converter with 10V to 16V input range. The output voltage is adjustable from V_IN to 48V. And the output can supply a 10A maximum load current. The demo board has a LTC7841 controller, which is a 60V dual-phase single output boost controller with digital power system management. Please see the LTC7841 data sheet for more detailed information.

The DC2798A powers up to default settings and produces power based on the command from the 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, view telemetry of voltage, current, temperature and fault status.
