EVAL6563-80W: PFC 88 ~ 264 Vin, 220 ~ 390 Vout

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.
