Applications Interleaved PFC is gaining popularity • Lower system cost from ripple-current • Digital TV in external and embedded-type power- cancellation • Telecom power supplies and rectifiers supply architec tures. It is exceptionally • Enables ultraslim and high-density • Professional and consumer audio flexible and provides many cost-saving designs • Merchant power supplies features such as passive-component • Lower total inductor volume • Air conditioning and refrigeration size reductions, smaller EMI filter ing • Smaller or lower-cost EMI filter and compressors components and higher efficiencies. TI output capacitors • Variable-speed motors offers both transition mode (UCC28063) • Facilitates higher efficiency • Low-profile power-supply applications and continuous conduction mode (CCM) (UCC28070) control methods. Other benefits of interleaving include scalability and ultrathin designs. Scalability allows for addressing many different power levels and applications.
