Web1 Easy: R19 provides power to start the IC up when it has not started switching yet. For the power from the aux. winding to be available the IC has to start switching first. Without R19 it is not getting any power ! You would then have a no chicken and no egg situation ;-) – Bimpelrekkie Mar 8, 2016 at 17:48 WebYes you can remove the auxiliary winding. It just produce a bias voltage so the VCC can take power from this winding instead of the internal VCC regulator (LDO). When you …
