This is the drain of the high-side MOSFET, typically connected to the input DC link voltage.
This pin is connected to the inverting input of the PWM comparator internally and to the
opto-coupler externally. The duty cycle is determined by the voltage on this pin.
This pin programs the switching frequency using a resistor.
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.
This pin is the power ground. This pin is connected to the source of the low-side MOSFET.
This pin is the supply voltage of the control IC.
No connection.
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.
