SenseFET drain. This pin is the high-voltage power SenseFET drain. It is de-
signed to drive the transformer directly.
Ground. This pin is the control ground and the SenseFET source.
Power Supply. This pin is the positive supply voltage input. During start-up,
the power is supplied by an internal high-voltage current source connected to
the V
is disabled and the power is supplied from the auxiliary transformer winding.
Feedback. This pin is internally connected to the 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 6.0V, the overload protection is activated, re-
sulting in shutdown of the FPS™.
No Connection.
Start-up. This pin is connected directly to the high-voltage DC link. At start-up,
the internal high-voltage current source supplies internal bias and charges the
external capacitor connected to the V
