Current return for driver and control circuits 2 FB Feedback. Directly connected to the opto-coupler 3 BOK Brownout Protection Pin. Connected to a resistor divider from the ground to bulk capacitor for setting the brownout level and line compensation. When the voltage of this pin is lower than 0.5V and lasts 35ms, the PWM signal will be off and system enters the auto recoverable protection mode (hiccup mode). Moreover, this pin is also applied for line OVP (trigger level is 4V) and line compensation (compensate the current sense for over load protection.) 4 RI Set the bias current to determine the normal switching frequency 5 ADJ To adjust the level of skip cycle. When its value is greater than 4.5V, the system will be latched 6 SENSE Current sense 7 VCC Supply voltage of driver and control circuits 8 GATE Gate driver output |
