... The operating frequency is limited by minimum t off to 8µs in FAN6300A and 13µs to 3µs in FAN6300H, so FAN6300H can operate at higher switching frequency than FAN6300A. FAN6300A/H controller also provides many protection functions. Pulse-by-pulse current limiting ensures the fixed-peak current limit level, even when a short circuit occurs ...

... FB The input impedance of this pin is a 5kΩ equivalent resistance. A 1/3 attenuator connected between the FB and the PWM circuit is used for the loop-gain attenuation. FAN6300A/H performs an open-loop protection once the FB voltage is higher than a threshold voltage (around 4.2V) more than 55ms. Input to the comparator of the over-current protection. A resistor senses the switching current ...
