than the number of phases used times the output voltage).
The output ripple amplitude is also reduced by the number
of phases used when all of the outputs are tied together
to achieve a single high output current design.

APPLICATIONS INFORMATION
The LTM4620A device is an inherently current mode
controlled device, so parallel modules will have very good
current sharing. This will balance the thermals on the
design. Figure 26 shows an example of parallel operation
and pin connection.
