Figure 4.5: Lamp Voltage and Arc Current during preheat and ignition
It should be noted in this example that the VCO voltage and consequently the ballast
frequency varies only by quite a small amount between the four different dimming levels,
although the lamp arc current varies considerably. This is because the system is operating
above the point in the dimming response curve known as the "knee", this is illustrated
below.

R6 is also required in order to ensure that the DIM pin of IC1 will be biased above 0V
before the voltage at VCC exceeds the UV+ threshold at startup. This prevents the
IRS2530D from shutting down during the first few cycles of hard switching that occur
when the half bridge starts to oscillate at maximum frequency.
