Thanks Jane 11. Definitely useful information.Recently I needed to repair a power supply which was controlled with IC( 6pins +1 missing).
It was ICE2A0565 (Off-Line SMPS Current Mode Controller) by Infineon.Unfortunatelly pin 2 was missing and you have 6pin missing.
But I think that a principle can be very similar( if not made also by Infineon)
