Description
This is the supply voltage of the high-side gate-drive circuit IC.
This is the drain of the low-side MOSFET. Typically, a transformer is connected to this pin.
This is the high-side gate driving signal.
No connection
No connection
This pin is for discharging the external soft-start capacitor when any protection is triggered.
When the voltage of this pin drops to 0.2V, all protections are reset and the controller starts
to operate again.
No connection
This pin programs the switching frequency. Typically, an opto-coupler is connected to control
the switching frequency for the output voltage regulation.
This pin senses the current flowing through the low-side MOSFET. Typically, negative
voltage is applied on this pin.
This pin is the control ground.
No connection
This pin is the supply voltage of the control IC.
No connection
This is the low-side gate driving signal.
No connection
This pin is the power ground. This pin is connected to the source of the low-side MOSFET.
