Function
Power supply ground
The power supply of the IC and this terminal is also used for the feedback control
Not connected
The PWM output is directly connected to the emitter of NPN transistor or the source
of MOSFET
It is used for line voltage compensation, and PWM uses this to terminate the output
switch conduction
It is used for short circuit protection, and this terminal will be pulled down to low
level when short circuit happens at the load side
