Description

Demonstration circuit 2481B-A is a high efficiency, high density, μModule® regulator with 4.5V to 15V input range. The output voltage is adjustable from 0.6V to 1.8V, and it can supply 86A maximum load current. The demo board has 1× LTM®4677 and 1× LTM4650 μModule regulators. The LTM4677 is a dual 18A or single 36A step-down regulator with PMBus power system management, and the LTM4650 is a dual 25A or single 50A step-down regulator. Please see LTM4677 and LTM4650 data sheets for more detailed information. DC2481B-A powers up to default settings and produce 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® onto your PC and use Analog Devices 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.
