UCC28065 Datasheet (Texas Instruments)

UCC28065, PFC Controller

The UCC28065 interleaved PFC controller enables transition mode PFC at higher power ratings than previously possible.

The device uses a Natural Interleaving™ technique to maintain a 180-degree phase shift.

Both channels operate as masters (there is no slave channel) synchronized to the same frequenc
