●Demonstration circuit 1740A is a PolyPhase® synchronousbuck converter featuring the LTC®3880EUJ, a dual-phase current mode controller with PMBus interface and digital power system management functions. There are two versions of the boards available:
■DC1740A-A: 4-phase single-output configuration. Default output setting VOUT0 = 1.2V/80A
■DC1740A-B: 3+1-phase dual-output configuration. De-fault output setting VOUT0 = 1.5V/20A, VOUT1 = 1.2V/60A
●The DC1740A powers up to default settings and pro-duces powerbased on configuration resistors or with non-volatile memory (NVM) settings without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter aspects of the LTC3880. To fully explore the extensive digital power manage-ment features of the parts, download the GUI software LTpowerPlay™ onto your PC and use LT C’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.
