Description
LTM4676EY
High Efficiency, PolyPhase
®
, DC/DC
Step-Down μModule Regulator with
PMBus Power System Management
Demonstration circuit 2106A-B 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 130A maximum load current. The demo board
has 1
×
and 3
×
LTM4630 µModule regulators.
The LTM4676 is a dual 13A or single 26A step-down
regulator with PMBus power system management, and the
LTM4630 is a dual 18A or single 36A step-down regulator.
Please see LTM4676 and LTM4630 data sheets for more
detailed information.
DC2106A-B powers up to default settings and produces
power based on configuration resistors without the need
for any serial bus communication. This allows easy evalu-
ation 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
