Hello

Page 4 of AN1792 (below) shows how the ZCD pin of the L6562 PFC controller can be used in making the L6562 operate in Constant Off Time mode.
Do you think that the L6564 can be used in the same way?
The ZCD pin of L6564 is certainly identical but we just wondered is there any hidden function which may mess things up here?

(sorry this question appears related to my previous but in truth, the intricacy means the questions seem better separated)
