Generation FL-Controller for FL-Ballasts
Functional Description
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
= 130 µA – phase 1 Figure 5)
VCC
and Start Up Hysteresis (I
= 160 µA – defines the start up resistors – phase 2 Figure 5) phases.
VCC
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
1
above 2.5 mA, an external Zener diode (D9 Figure 3) is required.
