DC2652A-A

DC2652A-A demonstration circuit is an 8-phase dual-output, high efficiency, high density, synchronous buck converter with 7V to 14V input range. Each output can supply up to 120A maximum load current with 1V output. The demo board showcases the LTC3888, which is a PMBus-compliant dual loop 8-phase step-down DC/DC controller with digital power system management. The LTC3888 is designed to work with DrMOS devices that provide an output current sense and temperature monitor. DC2652A-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.
