This pin is the high voltage power SenseFET drain. It is designed to drive the
transformer directly.
This pin is the control ground and the SenseFET source.
This pin is the positive supply voltage input. Initially, During start up, the power is
supplied through the startup resistor from DC link. When Vcc reaches 12V, the
power is supplied from the auxiliary transformer winding.
This pin is internally connected to the inverting input of the PWM comparator.
The collector of an optocoupler 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 6.0V, the over load protection is activated resulting in shutdown of the
FPS.
This pin is not connected.
This pin is for the pulse by pulse current limit level programming. By using a
resistor to GND on this pin, the current limit level can be changed. If this pin is
left floating, the typical current limit will be 3.0A.
