Frequently asked questions
Does it work as a standalone power supply?
No. It is a switching IC that needs a complete flyback design, including the transformer, feedback, rectification and filtering, as described in the datasheet.
Is it safe to test it on mains voltage?
Mains voltage is dangerous. Test with an isolation transformer and proper protection, and never work on a live mains circuit without the right experience and equipment.
