Notes
1. Non-repetitive duty factor 3,3%.
2. The maximum supply voltage should be chosen so that during flyback the voltage at pin 5 does not exceed 60 V.
3. When V5-4 is 13 V and no load at pin 5.
4. See Fig.4.
5. Duty cycle, d = 5% or d = 0,05.
6. When pin 3 is driven separately from pin 1.
7. During normal operation the voltage V8-2 may not be lower than 1,5 V.
8. RL = 8 Ω; IL = 125 mA (r.m.s.).
9. If guard circuit is active.
10. With a 22 pF capacitor between pins 1 and 5.
