End of life – window comparator

End of life – window comparator
To detect the ageing of the lamp with particular attention to the effect appearing as
asymmetric rectification, a programmable window comparator has been introduced
(centered around “VREF” with amplitude “VW”) that triggers when the EOL-R voltage is
higher than VREF+ VW/2 or lower than VREF – VW/2.
By means of the resistor connected to the EOLP pin, it is possible to select:
1.
the sensing mode:
–
fixed reference: the centre of the window comparator (VREF) is fixed at 2.5V by an
internal reference;
–
tracking reference: the centre of the window comparator is the voltage at pin CTR
(that is a signal proportional to the PFC output voltage).
2.
the half-window amplitude (VW/2): 220mV or 720mV.
