Use diode series to output of CT before burden resistor, once side connect to ground other side connect to L Limit pin followed by RC filter
It's hardly possible to plug-in a hall current sensor without a negative auxiliary supply.
Yes, you know maximum input current, what's the problem?Let's assume I'm using the standard shunt resistor. How to dimension that shunt resistor? Like with any other PWM topology using current control, the maximum input current should produce a voltage drop at the magnitude of the internal threshold (1V, in this particular case)?
Yes, doesn't change the calculation based on maximum current.What about variable load? The internal threshold (1V) will be attenuated by the output voktage feedback signal, hence the input current should be limited at a lower value?
