Application circuit with controlling a 120 W halogen lamp
The sensing resistor RS and timing capacitor Ct should be dimensioned according to :
In normal conditions (VCC = 14 V, maximum brightness) the voltage drop across the sense
resistor must be 50 mV. The current limiter intervenes attwice the nominal current, Inom.
The timing capacitor Ct (Vct = 3.5 V) must be chosen so that the delay before intervention is
twice the duration 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 recommended value for Cs is 47 pF.
