9.2.3 Typical Application, Differential (2N), AD-Mode PBTL (Outputs Paralleled after LC filter)
TPA3221 can be configured in mono PBTL mode by paralleling the outputs before the LC filter (see Section 9.2.2) or after the LC filter. Paralleled outputs after the LC filter may be preferred if: a single board design must support both PBTL and BTL, or in the case multiple, smaller paralleled inductors are preferred due to size or cost. Paralleling after the LC filter requires four inductors, one for each OUT_x. This section shows an example of paralleled outputs after the LC filter.
