DESCRIPTION
Demonstration circuit 2702B-B is a single output, dual-
phase, high efficiency, high density, µModule
with a 4.5V to 16V input range. The output voltage is
adjustable from 0.5V to 1.8V and can supply 100A maxi-
mum load current. The DC2702B-B demo board has a
LTM
4700
µModule regulator, a dual 50A or single 100A
®
step-down regulator with digital power system man-
agement. Refer to the LTM4700 data sheet for more
detailed information.
DC2702B-B powers up to default settings and produces
power based on configuration resistors without serial bus
communication. This feature allows easy evaluation of
the DC/DC converter. To fully explore the extensive power
system management features of the LTM4700, download
