Description
This pin is the high-voltage power SenseFET drain connection.
This pin is the control ground and the SenseFET source.
This pin is the positive supply input. This pin provides internal operating current for both startup
and steady-state operation.
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 7.5 V, the overload protection
triggers , which results i n the FPS? shutting down.
This pin is internally connected to the sync detect comparator for quasi-resonant switching. In
normal quasi-resonant operation, the threshold of the sync comparator is 4.6 V / 2.6 V. Whereas,
the sync threshold is changed to 3.0 V / 1.8 V in an extended quasi-resonant operation.
