LTC7051

Demonstration circuit DC3170A‐A/‐B features the LTC7883 and LTC7051 in a high current, high efficiency 4-phase step-down converter. The LTC7883 itself is a 4-channel, 4-phase, voltage mode step‐down controller with a PSM interface. The LTC7051 is a SilentMOS™ smart power stage that integrates high speed drivers with low RDS(ON) MOSFETs. The DC3170A‐A/‐B comes in two different assembly types, which are specified below:

DC3170A‐A: LTC7883 + LTC7051 Demo Board with Four Outputs

• V_OA0 = 0.75V/50A
• V_OA1 = 0.9V/50A
• V_OB0 = 1.0V/50A
• V_OB1 = 1.2V/50A

DC3170A‐B: LTC7883 + LTC7051 Demo Board with Single Output

• V_OUT = 1.0V/200A, 4‐phase

The DC3170A‐A/‐B operates with a switching frequency of 500kHz over an input voltage range of 7V to 14V. Each LTC7051 is driven by a three‐state PWM output of the LTC7883, while the LTC7051’s current sense and temperature outputs are monitored by the LTC7883. The DC3170A‐A/‐B does not require external serial bus communications to run. It uses settings pre‐programmed in the non-volatile memory of the LTC7883.

To fully explore the extensive power system management features of the LTC7883, download LTpowerPlay® onto the PC and use ADI’s I2C/SMBus/PMBus dongle DC1613A to connect to the board. LTpowerPlay allows the user to reconfigure the LTC7883 while running, store the configuration in non-volatile memory, view telemetry of voltage, current, temperature, fault status, and more. For more details and instructions on LTpowerPlay, see the LTpowerPlay Software GUI section of this manual. The LTC7883 and LTC7051 data sheets provide a complete description of the IC operation and application information and must be read in conjunction with this demo manual.

• Input voltage range: 7 V to 14 V
• Output voltage V_{OUT Max output current: 400 A}
• Number of phases: 8
• Current sense
• Temperature monitor
• PM bus compliant with digital power system management

Demonstration circuit DC2888A-A/DC2888A-B is an 8-phase single- output, high efficiency, high density, synchronous buck converter with 7 V to 14 V input range. The output can supply up to 400 A maximum load current. The demo board showcases one LTC3888/LTC3888-1 working with eight LTC7051. The LTC3888/ LTC3888-1 is a PMBus-compliant dual loop 8-phase step-down DC/DC controller with digital power system management. LTC7051 is an integrated smart power stage with current sense and temperature monitor. Refer to the LTC3888/LTC3888-1 and LTC7051 data sheets for detailed information.

DC2888A-A/DC2888A-B powers up to default settings and produces 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 ™ on your PC and use Analog Devices' I²C/SMBus/PMBus dongle DC1613A to connect to the board. LTpowerPlay allows to reconfigure the part on the fly and store the configuration in electrically erasable programmable read-only memory (EEPROM), and view the telemetry of voltage, current, temperature, and fault status.
