FUNCTIONAL DESCRIPTION (Continued)
the lamp fails to strike or is out of socket. Typically this
time is set to be fairly long by choosing a large value
of RX.
LFB OUT is ignored by the oscillator until CX reaches 6.8V
threshold. The lamps are therefore driven to full power and
then dimmed. The CX pin is clamped to about 7.5V.
A summary of the operating frequencies in the various
operating modes is shown below.
