Description
General part information
L6563H Series
The L6563H is a current-mode PFC controller operating in transition mode (TM) 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% at Tj = 25 °C) internal voltage reference. Loop's stability is optimized by the voltage feedforward function (1/V2correction), 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").
