Advanced Transition-Mode PFC Controllers

STMicroelectronics' current mode Power Factor Correction (PFC) controllers

STMicroelectronics L6563S/L6563H/L6564D PFC ControllersSTMicroelectronics' L6563S, L6563H, and L6564D are current mode Power Faction Correction (PFC) controllers that operate in transition mode. These devices offer improved performance and additional features compared to the well-known L6562A. This family of PFC controllers has low THD, improved loop stability and better transient response. The L6563S and L6563H provide options for tracking functions and an interface with the PWM controller of the DC/DC stage. Increased functionality allows greater ease for compliance to energy saving norms like Blue Angel, Energy Star, and Climate Savers.

  Features   Applications
  • Tracking boost function
  • Interface for cascaded converter’s PWM controller
  • Protection against feed back loop failure
    (latched shutdown)
  • Input voltage feed forward
  • Inductor saturation protection
    RoHS Compliant
  • Adaptors for notebooks
    (or notebook computers)
  • LCD TVs
  • AC-DC power supplies for
    industrial systems
  • Audio systems
  • POE equipment
