Product Details

The demonstration circuit DC3034A-A is a 2-phase single-output, high efficiency, high density, synchronous buck converter with a 7 V to 14 V input range. The output can supply up to 100 A maximum load current with 1 V output. The demo board features the LTC3884-1 controller paired with the LTC7051 smart power stage to provide a 2-phase buck converter solution. The LTC3884-1 is a dual output PolyPhase step-down controller with digital power system management. The LTC7051 is a monolithic smart power stage that integrates high-speed drivers with low resistance half-bridge power switches plus comprehensive monitoring and protection circuitry in an electrically and thermally optimized package. Refer to the LTC3884-1 and LTC7051 data sheets for detailed information.

The DC3034A-A powers up to default settings and produces power based on configuration resistors (or with the default setting in the nonvolatile memory of the DC3034A-A) without the need for any serial bus communication, which allows easy evaluation of the DC-DC converter. To fully explore the extensive power system management features of the DC3034A-A, download the GUI software LTpowerPlay™ onto the PC and use the Analog Devices, Inc., I2C/SMBus/PMBus DC1613A dongle to connect to the board. LTpowerPlay reconfigures the device once connected and stores the configuration in an electrically erasable programmable read-only memory (EEPROM). LTpowerPlay also views the telemetry of voltage, current, temperature, and fault status of the demo board.
