TPS82084: Inductor size and tollerance.

Hi Klaus,

Thank you for designing with these simple devices.

The inductance value is written in the block diagram of each D/S.

It is not clear what is meant by size and tolerance (inductance tolerance or size tolerance?), but this is a standard, off the shelf inductor used.

Hi Chris,

An inductor size of 0.47uH was a little difficult to fine in the datasheet.

I would also like to know the inductors inductance tolerance. It is properly +/- 20% or 30% (0.47uH +/-20%)

The inductor part-number was just nice to have, because it would also give me the inductor inductance tolerance.

Best regards,

Klaus

Thanks for confirming the request.

We do not specify the inductor part number or tolerance. I'm curious what this would be used for? One of the purposes of using a power module is to have to deal with fewer components in order to simplify the design effort.

As a standard inductor, its tolerance would be around 20% or 30%.

Hi Chris,

We are making a module that our customer are going to use in an intrinsic design, and this intrinsic design require energy storage devices (inductors and capacitors) to be known.

I expected that you would not specify the coil used, this just give me some more work measuring a sample size of module inductors.

Can you tell me whether TPS82084 and TPS82085 are using the same inductor? This will half my work.
