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?
Hi Mr. K,
Table 13 in the data sheet lists Transformers that were characterised for use with the ADM2487E.
Which transformer are you using?
Is your transformer primary voltage 3.3V or 5.0V ?
Can you share your circuit schematic and part numbers?
