DESCRIPTION
LTM4664
48V
IN
, Dual 25A µModule Regulator
With Digital Power System Management
Demonstration circuit 2672A-A is a complete non-iso-
lated 48V input, dual-output, high efficiency, high density
µModule regulator with 30V to 58V input range. Each
output can supply 25A maximum load current. The demo
board has a LTM4664 µModule regulator, which is a dual
25A or single 50A step-down regulator with digital power
system management. Please see the LTM4664 datasheet
for more detailed information.
DC2672A-A 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
