Product Details

Demonstration circuit 2728A is a high voltage, dual output boost converter with 12V to 24V input range. The output voltage is adjustable from VIN to 48V. Each output can supply 5A maximum load current. The demo board has a LTC7880 controller, which is a 60V dual output step-up controller with digital power system management. Please see LTC7880 data sheet for more detailed information.

DC2728A powers up to default settings and produces power based on configuration resistors or its nonvolatile memory (NVM) 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.
