    Hi Nandakumar,

    I do not have the core and winding information for the transformer, but here are the electrical specs:

    -          

    -          Switching frequency ~75kHz

    -          14:1:3 ratio (primary:secondary:bias)

    -          900uH primary inductance

    -          Primary current ~ 500mA (peak) and 150mA (rms)

    -          Secondary current ~ 2.6A (rms)

    -          Shield winding

    regards,

    Brian
