DESCRIPTION

LTM4700

High Current, PolyPhase® Step-Down

Power µModule Supply with Digital Power

System Management 3 × LTM4700, 300A

Demonstration circuit 2784B-B is a high efficiency, high

density, µModule® regulator with 4.5V to 16V input range.

The output voltage is adjustable from 0.5V to 1.8V and it

can supply 300A maximum load current. The demo board

has three LTM®4700 µModule regulators, 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.

DC2784B-B 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
