DC2881A-A：LTC7050/LTC3884-1 2-Phase, Dual-Output Synchronous Buck Converter with Power System Management

Demonstration circuit 2881A-A is a 2-phase dual-output, high efficiency, high density, synchronous buck converter with 7V to 14V input range. Each output can supply up to 30A maximum load current with 1V output. The demo board features the LTC3884-1 controller paired with the LTC7050 dual smart power stage to provide a 2-phase buck converter solution. The LTC3884-1 is a dual output poly phase step-down controller with digital power system management. The LTC7050 is a dual monolithic smart power stage which integrates high speed drivers with low resistance half-bridge power switches plus comprehensive monitoring and protection circuitry in an electrically and thermally optimized package. Please refer to the LTC3884-1 and LTC7050 data sheet for more detailed information.

DC2881A-A powers up to default settings and produces power based on configuration resistors (or with the setting in its non-volatile memory) 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.
