PowerSeminar-2Interleaved PFC technology bring up low ripple and high efficiency 1 Proprietary Information Presentation Outline 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 ……
