Figure 3. Examples of 2-Phase, 4-Phase, and 6-Phase Operation with PHASMD Table

is greater than the number of phases used times the out-

put 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.

The LTM4620A device is an inherently current mode con-

trolled 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.
