ADM2487E: D1/D2 pin


I have a question about the D1/D2 of ADM2487E.

I am using ADM2487E with the same circuit as Figure34 in the datasheet.

In my circuit, When VDD1 reaches about 1.4V, D1/D2 and GND are short-circuited.

And, the overcurrent flows to the transformer.

When the voltage of VDD1 goes up further, D1/D2 starts oscillating.

I want to solve the problem of the overcurrent to the transformer until D1/D2 starts oscillating.

Could you tell me advice of the cause?

Best Regards,
