Description

Demonstration circuit 2605A is a high efficiency, high density, single-output buck converter with 7V to 14V input range. The output voltage is adjustable from 0.5V to 1.5V, and can supply up to 120A of load current with a 1V output. The demo board features the LTC®3884-1paired with a slave controller LTC3874-1 to provide a 4-phase buck converter solution. The LTC3884-1 is a dual output poly phase step-down controller for ultra-low DCR sensingwith digital power system management. The LTC®3874-1 is a dual PolyPhase® current mode synchronous stepdown slave controller. Please see LTC3884-1 data sheet for more detailed information. DC2605A powers up to default settings and produces power based on configuration resistors or with 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 LTC’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, viewtelemetry of voltage, current, temperature and fault status.
