Highlights
- The UCC28070 power factor corrector IC controls two CCM (Continuous Conduction Mode) Boost PFC power stages operating 180° out of phase with each other. This interleaving action reduces the input and output ripple currents so that less EMI filtering is needed and allows operation at higher power levels than a non-interleaved solution.
- the boost inductor size can be smaller than in a single-phase design
