DESCRIPTION
Demonstration circuit 2702A-B is a single output, dual
phases, high efficiency, high density, µModule regulator
with 4.5V to 16V input range. The output voltage is adjust-
able from 0.5V to 1.8V and it can supply 100A maximum
load current. The demo board has a
regulator, which is a dual 50A or single 100A step-down
regulator with digital power system management. Please
see LTM4700 data sheet for more detailed information.
DC2702A-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
