no-load consumption of this stage (0.5 1 W). There is no compliance issue in that because
EMC regulations on low-frequency harmonic emissions refer to nominal load, no limit is
envisaged when the converter operates with light or no load.
To do so, the L6599A provides pin 9 (PFC_STOP): it is an open collector output, normally
open, that is asserted low when the IC is idle during burst-mode operation. This signal will
be externally used for switching off the PFC controller and the pre-regulator as shown in
. When the L6599A is in UVLO the pin is kept open, to let the PFC controller start
first
