DESCRIPTION
Demonstration circuit 2784B-A is a high efficiency, high
density, μModule® regulator with 4.5V to 16V input range.
The output voltage is adjustable from 0.5V to 1.8V and it
can supply 200A maximum load current. The demo board
has two LTM®4700 μModule regulators, which is a dual
50A or single 100A step-down regulator with digital power
system management. See LTM4700 data sheet for more
detailed information.
The DC2784B-A 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 graphical user interface (GUI)
software LTpowerPlay® onto your PC and use Analog
Devices I2C/SMBus/PMBus dongle DC1613A to connect
to the board. The 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.
