TPS82085: Inductor used in TPS82085SIL module

herbert

Part Number: TPS82085

I'm trying to figure out what inductor is used in the TPS82085SIL modules and where I can find the datasheet (for the inductor)?

The TPS82085 datasheet only says that it is 0.47uH nothing else.

Thanks in advance,

Herbert

Hi Herbert,

I remembered that this same question came up recently, so I searched the forum (at the very top of the page) for 'TPS82085' and found this thread: e2e.ti.com/.../647260

So basically the inductor is a TI trade secret or am I reading this thread wrong?
Personally I'm interested in the inductor type and build to model EM emission.

Thanks,
Herbert

I wouldn't state it like that. It is a standard, off the shelf chip inductor. These are shielded. You can sample the device and remove the inductor if you want to study the inductor itself, but one of the primary purposes of a power module is to simplify the design.
