The duration of the Preheat mode as well as the mode of operation of the ballast are determined by the
voltage on the CPH pin of the IRS2166D. At the completion of the UVLO mode, Preheat mode is
entered and an internal current source is activated at the CPH pin of the IR2166, which begins to
charge up capacitor CPH. The ballast remains in the Preheat mode until the voltage on the CPH pin
exceeds the Ignition Ramp mode threshold (10 V).
16. Ignition Ramp Mode
At the completion of the Preheat mode the ballast switches to the Ignition Ramp mode and the
frequency ramps down to the run frequency. Resistor RPH is no longer connected directly in parallel
with resistor RT so the run frequency is determined only with RT. During this ramping downward of
the frequency, the voltage across the lamp increases in magnitude as the frequency approaches the
resonant frequency of the LC load circuit until the lamp ignition voltage is exceeded and the lamp
ignites. The maximum ignition voltage that can be generated is determined from the value of RCS, but
in any case the ignition frequency must be higher than the run frequency. Figure 5 shows the ramping
of voltage appearing across the lamp.

During the Ignition Ramp mode the voltage on the CPH pin of the IRS2166D continues to ramp up
until the voltage at the CPH pin of the IRS2166D exceeds the Run mode threshold (13 V). Over-
current sensing and fault counter are enabled during Preheat and Ignition modes. A full explanation of
the functionality of the over-current sensing is in the section on Fault Mode.
