Notification 107 - Optimization failed: Change device and/or Transformer selection

ISSUE / RESULT

FIX / REFERENCE(S)

Failure

Optimization failed to find a solution.

Possible manually selected larger PI Component, the optimization engine starts with the chosen device and, in the order of increasing power levels, steps through the remaining PI Components and transformers.  Only those transformers with adequate power rating (PMax) are considered.

Specified power requirements may be incompatible with the PI Component  and/or the transformer.

• Try reducing the size of the
  PI Component   and/or the transformer, then retry the optimization.  The initial choice(s) may be too large to complete the design.

• Change the optimization type, then retry it.

• Change the transformer region (Transformer Advanced Parameters tab), then retry the optimization.

• The transformer may be rated for less power than the output requires.  Consider adding a larger Custom transformer to the list.  Note: Increasing the winding area (AW) window will increase the transformer power rating (PMax).

• See the TNY264-268, TOP232-234, and   TOP242-250 Data Sheets Output Power Tables for maximum power handling capabilities.
