Step 4: Program Preheat Time
i PK
The preheat time is defined by the time it takes for the
capacitor on pin CPH to charge up to 12 V. An internal current
source of 3.6 μA (I CPH ) flows out of pin CPH. The preheat time
is therefore given as:
Note: The PFC inductor must not saturate at over
the specified ballast operating temperature range. Proper
core sizing and air-gapping should be considered in the
inductor design.

The maximum ignition current is programmed with the external
resistor R CS and an internal threshold of 1.20 V. This threshold
determines the over-current limit of the ballast, which can be
exceeded when the frequency ramps down towards resonance
during ignition and the lamp does not ignite. The maximum
ignition current is given as:
