hey guys...
can any one please identify the type of SMPS ; the circuit I have attached here.
I have used TOP261 switch for switching purpose which is MOSFET basically.

but I don't know which type i have designed..
I mean is it buck, boost or flyback or anything else...
plz rply me fast.
nd also mention how it is different from other types??

thank you all

It is a flyback converter. Hint: inverted secondary(ies) winding dots compared to primary, means flyback. If the windings were used in the same polarity (dots in the same position - top or bottom), you would have a forward. Also, flyback transformers usually have a gap (not discernible in a transformer schematic depiction), and the diodes in the secondary have a different topology, the flyback ones being simpler.
