Default Question about IC Power Supply Winding

Hi guys,

I was reading an application note when I came up with this:


I have seen another design where this auxiliary winding was in the primary.

Can someone explain Me what are the differences between placing that aux. winding in the primary or in the secondary?

Isn't a little bit ambiguous placing the aux. winding the the secondary while the Controller is at the primary side?

There is no such thing as 'in the primary' or 'in the secondary'. The winding connected to the supply or excitation is the primary. All other windings are secondaries. It does not matter which side of the core the windings appear in the circuit diagram.
