Hi,
how regulating current is done?
My first made power supply with uc3845 has current regulation done by varying duty cycle on primary side (energy regulation).
If i want constant current with buck regulator i sense voltage on shunt resistor (0,01R) 10mA lowest, multiply it by 100, compare it and then turn feedback pin IC to ground.
But i am aware of hysteresis. What do you think about it? Thanks?
