Ultrathin Dual 14A or Single 28A µModule Regulator
DESCRIPTION
Demonstration circuit 3089A is a dual-output, high effi-
ciency, high density, µModule regulator with 2.7V to 5.75V
input range. Each output can supply 14A maximum load
current. The demo board has a
regulator, which is a dual 14A or single 28A step-down
regulator with digital power system management. Please
see LTM4686B data sheet for more detailed information.
DC3089A powers up to default settings and produce
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
the GUI software LTpowerPlay™ onto your PC and use
