IRPLCFL1
Functional Description (continued)
The frequency shifting is accomplished by switching out different capacitors used to
program the oscillator frequency. The capacitors are switched out by shorting them with
MOSFET’s which are timed to turn on at different times. The pre-heat frequency is determined
by the following formula:

The pre-heat time is determined by an RC combination formed by R3 and C3 and the
voltage of zener diode D1. When the voltage across C3 reaches the magnitude of the zener
diode D1 + the turn-on threshold of Q1, capacitor C6 is shorted out and the frequency shifts to
the final running frequency. The final running frequency is given by the formula:

The final component values, shown in Bill of Materials, were chosen to operate a 13 watt
compact fluorescent lamp with a cathode resistance at cold of 4 ohms. If a lamp is used which
has a different cathode resistance the component values for the pre-heat frequency selection
will need to be changed. The ballast circuit was operated at various temperatures from 25
degrees C to 105 degrees C with little or no change in the operating characteristics.
