UCC28700 NO LOAD STABILITY PROBLEM

ear sir,

the inductance when measured across the primary by shorting each output is given below

27ve output when shorted = 276uH

15ve output when shorted = 262uH

18vspm output when shorted= 380uH

12vd output when shorted= 440uH

8vd output when shorted = 449uH

24Vsmps output when shorted = 730uH

I have a doubt whether the values are coupling inductances ???. because Aux winding and primary winding are right next to each other ,leakage inductance of 711uH is impossible.

Note that i measured the inductance by keeping the RLC meter setting as series inductance .
