DESCRIPTION
Demonstration circuit 3190A-D is a high current, high
density, high efficiency open-frame μModule
tor with 45V to 65V input range. The demo board has
a
LTP™8803-1A
μModule regulator which provides
microprocessor 1.15V voltage from 54V power distri-
bution architecture with digital power system manage-
ment. The maximum output current for the demo board
is 160A. Please see LTP8803-1A data sheet for more
detailed information.
DC3190A-D 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
