ness) the voltage drop across the sense resistor

must be 50 mV. The current limiter intervenes

so that the delay before intervention is twice the du-

ration of the current limitation at power-on.

The optimal value of the oscillator frequency, taking

tolerances into account, must be slightly higher than

the frequency at which lamp flicker is noticable (min

60 Hz).

The switching times are a compromise between

possible EMI and switching power losses. The rec-

ommended value for Cs is 47pF.
