DS92LV2421: DS92LV2421 - VDDTX, VDDHS, VDDP, VDDL & VDDIO - Individual currents for these different supplies pins.

Hi Dhoresh,

We'll look into this and get back to you shortly.

Hi Dhoresh,

Figure 38 on page 43 of the datasheet shows ferrite beads with 1kΩ impedance and DC resistance less than 1Ω on each power supply input. Is this enough information to help with selection of FBs?

Hello I.K,

Thank you for your response.

My main concern is related to current of FB. I need to justify selection of FB with respect to current point of view. 

When I check for derating of FBs used, I need current parameter. Please help me with individual currents rather specifying FB specifications. 

Thanks,

Dhoresh.

Hi Dhoresh,

Sorry for the delay. I have asked around and it doesn't look like we have this data. Since the the total supply current is listed in the datasheet, I believe it would be best to make your FB selection based on the assumption that each pin consumes around the same amount of current. To be on the safe side you could also assume that each pin consumes the same amount as the typical total supply current (though this is not the case).
