How much current need to be fed to VCC1

Part Number: ISO1212

Hi,

We want to use 16 pcs ISO1212 so we need a 5V power to VCC1 of ISO1212.

How much is the output current of the power solution (Buck) for 16 pcs ISO1212 at least?

Thank you.

    Hi Cindy,

    As stated in ISO1212 datasheet (also copied below), each unit of ISO1212 is going to consume a typical current of 1.2mA and a maximum current of 1.9mA. Hence, for 16 devices, the min current to be supported by the power supply solution should be 30.4mA. Thanks.
