Description
No connection
This pin is connected to a storage capacitor. A high-voltage regulator connected between pin 8
(V STR ) and this pin provides the supply voltage to the FSQ500N at startup and when switching
during normal operation. The FSQ500N eliminates the need for auxiliary bias winding and
associated external components.
This pin is internally connected to the non-inverting input of the PWM comparator. The collector of
an opto-coupler is typically tied to this pin. For stable operation, a capacitor should be placed
between this pin and GND. If the voltage of this pin reaches 4.5V, the overload protection triggers,
which shuts down the FPS.
This pin is the control ground and the SenseFET source.
