Regulator with Digital Power System Management
DESCRIPTION
Demonstration circuit 2863A features the
which is a dual 30A or single 60A µModule
with a 4.5V to 16V input range. Two LTM4680 µModule
ICs are paralleled on this board to deliver 120A maximum
load current. The output voltage is adjustable from 0.5V to
3.3V. Refer to the LTM4680 data sheet for more detailed
information.
The DC2863A powers up to default settings and pro-
duces 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
LTM4680, download the GUI software LTpowerPlay
