regulator with 4.5V to 16V
input range. The output voltage is adjustable from 0.5V
to 33V and it can supply 50A maximum load current. The
demo board has a
µModule regulator, which is
a dual 25A or single 50A step-down regulator with digital
power system management. Please see LTM4678 data
sheet for more detailed information.
DC2570A powers up to default settings and produces
power based on configuration resistors without the
need for any serial bus communication. This allows
easy evaluation of the DC/DC converter. To fully explore
