COMP

Voltage feedback pin (same as the COMP pin in UC384X). Connect

a photo-coupler to close the control loop and achieve the regulation.

BNO

Brownout Protection Pin. Connect a resistor divider between this pin

and bulk capacitor voltage to set the brownout level. If the voltage

below the threshold, the PWM output will be disabled.
