Figure 3, Preheat/Ignition/Dim Mode timing diagram.
The resonant output stage transitions to a series-L, parallel-RC circuit with the Q-value and operating point
determined by the user dim level (Figure 4). If the lamp does not ignite, the voltage on pin VCO continues to
increase and the frequency continues to decrease until the VCO voltage exceeds V VCOFLT+ (4.0V, typical) and
the IC enters Fault Mode and shuts down. The minimum frequency should be set below the high-Q
resonance frequency of the ballast output stage to ensure that the frequency ramps through resonance for
lamp ignition (Figure 4). The desired preheat time can be set by adjusting the slope of the VCO ramp with
the external capacitor, CPH.
