Dual 50A or Single 100A µModule Regulator
DESCRIPTION
Demonstration circuit 2702A-A is a dual-output, high
efficiency, high density, µModule regulator with 4.5V to
16V input range. Each output can supply 50A 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-A 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, down-
load the GUI software LTpowerPlay™ onto your PC and use
