Topswitch-gx device is not Loading

Led Driver designed for 52V,700mA,for no load it gives 60V Output,but on Resistive load of 80R it gives only Vo=20V,Io=230mA,what may be the reasons for this,i checked the widings direction,Inductance,but its the same,can you please provide me the solution as eearliest please,
Herewith attaching design File & Transformer Document

Hi,
Verify the actual output current for an LED load. It should match with a resistive load.
If it is not 700mA, adjust the bias of the transistors.
