ISO3086T oscillator supply

Other Parts Discussed in Thread: ISO3086T

Hello Team,

We have a query for ISO3086T isolated power,

3.3V is being used for VCC1, primary side supply of device.

However to generate secondary side isolated supply of 5V, a separate 5V is available on primary side as shown in attached schematic.

Is it OK to use 5V with transformer when device primary side is powered through 3.3V, will it damage the device D1 and D2 pins?

Thanks and regards, 

Mahendra
