Description
LTM4676
Dual Step-Down µModule
Regulator with PMBus Digital
Power System Management
Demonstration circuit 1811B-A 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
µModule
regulator, which is a dual 13A or single 26A step-down
regulator with PMBus power system management. Please
see LTM4676 data sheet for more detailed information
The DC1811B-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 GUI
software LTpowerPlay™ onto your PC and use LTC’s I
2
C/
SMBus/PMBus dongle DC1613A to connect to the board.
