The mean value is Io = 1 T ∫ Io (t) dt 0 T ; 4. The outputs are switced off for Vcc ≤ Vccu. The logic is not reseted. For a reset, RES1 or RES2 must be used. 5. This current is measured in the GND - terminal when one single output is in flyback and consists of the supply current added to the value of the output current source and the leakage current of the flyback diode. This leakage current is less than 1% of the nominal flyback current. 6. The PWM frequency is defined by an external capacitor. The PWM oscillator frequency is: fpwm = fosc 32 with fosc = Kf Cosc ⋅ 1A/V and kin =15 ⋅ 10-6; the range is: 300Hz ≤ fpwm ≤ 3000Hz. The OSC Pin can be alternatively driven by an external TTL / CMOS signal. 7. For Iout ≥ Ioutl an internal comparator switches the corresponding output off for the current PWM cycle. L9341 3/10 |
