Interleaving consists of paralleling two small stages in lieu of a single big stage. This approach has several merits like ease of implementation, ability to use smaller components, and better distribution of heating. These attributes make the interleaved PFC topology attractive to slim form factor applications such as flat panel TVs and ultra-slim notebook adapters.180° out of phase operation Frequency foldback at low power Integrated Over current protection, overvoltage protection, UVLO, and brown-out protection Frequency clamped critical conduction mode (FcCrM) operation Low EMI and reduces RMS current in the bulk capacitor Improved light load efficiency Increased robustness with few external components Optimized efficiency over the load range
