DESCRIPTION
Demonstration circuit 1811B-B is a dual-output, high
efficiency, high density, μModule® regulator with 4.5V to
26.5V input range. Each output can supply 13A maximum
load current. The demo board has a LTM®4676A μModule
regulator, which is a dual 13A or single 26A step-down
regulator with PMBus power system management. Please
see LTM4676A data sheet for more detailed information.
The DC1811B-B 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 GUI software LTpowerPlay® onto your
PC and use ADI’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.
