Introduction to Interleaved transition mode PFC
Comparison to single-channel CCM PFC
Comparison to so-called “master/slave” architecture
Interleave technology benefit us.
Ripple cancellation to drive lower system cost
Improved efficiency via enhanced phase management to drive higher
system performance

 Continuous Transition Mode operation minimizes switching losses
associated with MOSFET junction capacitors (result of DCM operation)
TI Interleave solution: UCC28060
Faster transient response via slew rate comparator
“Fail Safe” OVP pin to provide additional system safety
Implementation of current limiting drives lower system costs, improved
reliability and higher efficiency
