    Hi everyone,

    I just found this circuit in Texas Instruments web bench design module which steps down 230 V AC to 12 V DC using the IC LM5023.
    (See attachment)

    Could someone please explain me briefly how this circuit works as I am not completely clear according to my understanding.
    And moreover , the cost of the transformer(T1) is not given when i downloaded the bill of materials. Could someone just tell me the approximate cost of such a transformer ?

    Thank you !!
