Product Overview

The L6563HTR is a current-mode Power Factor Controller operating in transition mode, which embeds the same features existing in the L6563S with the addition of a high voltage start-up source. These functions make the IC especially suitable for applications that have to be compliant with energy saving regulations and where the PFC pre-regulator works as the master stage. The highly linear multiplier, along with a special correction circuit that reduces crossover distortion of the mains current, allows wide-range-mains operation with an extremely low THD even over a large load range. The output voltage is controlled by means of a voltage-mode error amplifier and an accurate (1% @Tj=25°C) internal voltage reference. Loop's stability is optimized by the voltage feedforward function (1/V2 correction), which in this IC uses a proprietary technique that considerably improves line transient response as well in case of mains both drops and surges ("bidirectional").
  • Tracking boost function
  • Fast bidirectional input voltage feedforward (1/V² correction)
  • Interface for cascaded converter's PWM controller
  • Remote ON/OFF control
  • Accurate adjustable output overvoltage protection
  • Protection against feedback loop disconnection (latched shutdown)
  • Inductor saturation protection
