    dear friends,

    i m willing to make one 230v direct input (with out step down transformer) , 0 to 50v dc or 3v to 50v dc adjustable output power supply with max 3A current rating using smps ICs like uc 3843 or TL 494 and power MOS FETS.

    can any forum member please help me in providing schematic ?

    pls note i m not willing to use step down transformer, so LM 317 and other similar regulators based circuit may not help me.
