I just came across this SMPS circuit on the DigiKey website:
Is it really possible to implement a 12V 350mA output SMPS with wide mains input voltage without a transformer or an opto-isolator?
The datasheet for the VIPer22A shows transformers and opto-isolators used in various application circuits.
Is the design safe as there is no isolation between the input and output?
