This mode is in order to prevent a malfunction of the IC due to an instable system e.g. the lamp
parameters are not in a steady state condition. After finish the 625 ms Pre Run phase, the IC switches
over to the Run mode (phase 8 Figure 4) with a complete monitoring.
2.2.1 Operating Levels from UVLO to Soft Start
This chapter describes the operating flow from phase 1 (UVLO) until phase 4 (Soft Start) in detail. The
control of the ballast is able to start the operation within less than 100 ms (IC in active Mode). This is
achieved by a small Start Up capacitor (about 1µF C12 and C13 – fed by start up resistors R11 and
R12 in Figure 3) and the low current consumption during the UVLO (I
and Start Up Hysteresis (I
The chip supply stage of the IC is protected against over voltage via an internal Zener clamping
network which clamps the voltage at 16.3 V and allows a current of 2.5 mA. For clamping currents
above 2.5 mA, an external Zener diode (D9 Figure 3) is required.
