During the Startup Mode , the operating frequency is

CT = 220 pF
determined by the parallel combination of R PH ,
R START , and R T , combined with the values of C START ,
C T and R DT , as shown in Figure 6. This frequency is
normally chosen to ensure that the instantaneous
voltage across the lamp during the first few cycles of
operation does not exceed the strike potential of the
lamp. As the voltage across C START charges up to the
R T lead voltage, the output frequency exponentially

decays to the preheat frequency.
During the Preheat Mode, the operating frequency
is determined by the parallel combination of R PH and
R T , combined with the value of C T and R DT . This
frequency, along with the Preheat Time, is normally
chosen to ensure that adequate heating of the lamp
filaments occur. Typically, a 4.5:1 ratio of the hot
filament-to-cold filament resistance is desired for
