    Actually I need to design a SMPS(i/p 4.5-6V dc@ 800mA & o/p 25-28V dc@ 120mA) without using Transformer. I have only a bit of bookish knowledge on PWM, SMPS & as well as Bost & Buck converter & some hand on experiance on Linear power supply.
    I request every member of this forum to help me for designing such type of SMPS both theoritically & practically. If any one have practical idea about this ckt. Plz mention the ckt. diagram & parts list(which will be available in India).

    Looking for response. :(

    Hello,

    Did you already have a look at the MAX668 and MAX669 ?
    See datasheet.
