EVAL6563-80W
L6563 80W High performanceTM PFC with active
tracking boost function
Data Brief
General description
L6563 is a current-mode PFC controller operating in Transition Mode (TM). Based on the
core of a standard TM PFC controller, it offers improved performance and additional
functions, such as active tracking boost function. In some applications it may be
advantageous to regulate the output voltage of the PFC pre-regulator so that it tracks the
RMS input voltage rather than at a fixed value like in conventional boost pre-regulators. This
is commonly referred to as "tracking boost" or "follower boost" approach.
With the L6563 this can be realized by connecting a resistor between the TBO pin (pin 6)
and ground. The board implements a 80 W, wide-range mains input, PFC pre-regulator.
