I want to design a constant current supply based on the UC3842/3.
I see the chip provides the current sense input, can I use this pin as the current feedback to limit the current?
The mentioned threshold voltage is 1V. I'm not sure exceeding 1V will turn-off the PWM (short circuit use case) or reduce PWM duty cycle as the voltage feedback error amplifier does (2.5V reference).
