ISO3086T: Different supplies at VCC1 and Transformer Input

Priyansh Kharote

Part Number: ISO3086T

Everywhere in the datasheet Same supply is given to VCC1 and transformer input. Can we apply different supply voltages at VCC1 pin and Transformer input as shown in following Image?

Priyansh,

Unfortunately the included image from your post did not come though. Supplying a different voltage to the transformer driver vs Vcc1 seems possible within reason ex. VCC1 = 3.3V, transformer driver = 5V. What are the voltages you intend to use for your case?

Respectfully,

Lucas

Hi Lucas, I don't know why image is not visible.

Your guess is correct. I am planning to use VCC1 =3.3V and Transformer Primary Input = 5V.

So, as you mentioned it is possible to work with these voltage levels, right?

Priyansh,

Yes this indeed seems possible. Let me know if you have any further questions.

Respectfully,
