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?
Thank you for your reply.
I am using the transformer of Murata.
A primary voltage of the transformer is 3.3V.
And, I am using the ADP3330.
The difference with Figure34 in the datasheet is Schottky diode.
I am using Schottky diode of Shindengen for the second side of the transformer.
