For the NCP1207A, offline quasi resonant flyback controller........
1.....Can overload protection function be gotten rid of by putting a 3V9 zener on the FB pin?
1A.....Can overload protection function be gotten rid of by ensuring that Vcc never goes below 12V?
2.....When it goes into skip cycle due to light loading, does it always turn on 5us after the demag signal?...................in other words, true burst mode operation, where the FET does not switch on at all for say, 1ms, can never happen?
3.....Supposing i want the maximum voltage on the source current sense resistor to be 0.5V (instead of 1V), can i arrange this by adding a 2V1 zener diode to the FB pin?

....The datasheet doesnt really make these points too clear, unless its my interpretation?
