DEMO MANUAL DC2066A
LTM4677EY
Dual 18A or Single 36A µModule Regulator
With Digital Power System Management
Description
Demonstration circuit 2066A is a dual-output, high ef-
ficiency, high density, µModule regulator with 4.5V to
16V input range. Each output can supply 18A maximum
load current. The demo board has a LTM^®4677 µModule
regulator, which is a dual 18A or single 36A step-down
regulator with digital power system management. Please
see the LTM4677 data sheet for more detailed information.
DC2066A 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 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, view
telemetry of voltage, current, temperature and fault status.
