    design of isolated smps

    i m trying to design a isolated buck converter that will give me 5v fixed output
    Vin= 7v to 30V.
    i want to desing a pwm whose output is connected to transformer.
    PWM receives i/p from optocoupler which gets i/p from the output of buck converter.

    It would be very nice of u if u help me in this....

    Thanking in advance
