Functional description 7.1 Introduction The integrated circuit for electronically ballasted compact fluorescent lamps and its derivatives nominal mains voltage of 230 V (RMS). It provides all the necessary functions for proper preheat, ignition and on-state operation of the lamp. Besides the control function, the IC provides the level shift and drive for the two internal power MOSFETs ...

... NXP Semiconductors capacitor connected to pin CI. The frequency during preheating will be approximately 90 kHz. This frequency is well above the resonant frequency of the load, which means that the lamp is off. The load consists of L2, C5 and the electrode resistance only (see Figure The circuit can be locked in the preheat state by connecting pin CPAV to ground. During ...

... NXP Semiconductors 7.8 Feed forward frequency Above a defined voltage level at pin VDC the oscillation frequency also depends on the supply voltage of the half bridge (see oscillator is in this feed forward range and is derived from the current through R similar to pin RHV current). The feed forward frequency is proportional to the average value of the current (within its operating range) through R is clamped for currents beyond the operating range (i ...

Frequency < 75 kHz 75 kHz to 80 kHz > 85 kHz The drive voltage at gate of T2 (G2) will exceed the drive voltage of the high side driver. 7.12 Frequency and change in frequency At any point in time during oscillation, the circuit will operate between f change in frequency will be gradual, no steps in frequency will occur. Changes in frequency caused by a change in voltage at pin CI, show a rather constant df/dt over the entire frequency range ...
