Hello,
I have designed an SMPS with dual outputs of 5Vdc and 12Vdc and i have to prepare a datasheet for that SMPS. For that, i need to specify one parameter for minimum and maximum AC input voltage by which SMPS can function and give correct outputs. i have tested maximum input voltage of 440Vac which gives correct outputs of 5Vdc and 12Vdc. but i am unable to decide minimum AC input voltage. i had applied input of 9Vac through stepdown transformer, but there was no output i.e. 0Vdc o/p.
How can i decide minimum AC input that can give correct 5Vdc and 12Vdc outputs ?
