I need to design a 150V - 230V AC input to 5V, 1.5A DC output power supply which has two USB Outputs.
Should I go for the transformerless design or should I include a transformer?
In any of the above cases, what should be the circuit diagram?
I would appreciate your help on this point. Thanks in advance!
Go with the transformer. Step down the input voltage and do the conversion. Use a regulator which is able to provide 5V with 3A, As you said need two USB outputs. So 1.5A for both
