TPS61099: TPS61099 Inductor

Teach Me
Expert 1940 points
Part Number: TPS61099

Hi TI Experts,

We are using the TPS61099EVM, but we found out the inductor suggestion is mismatch.

At the datasheet, it is recommend to use Inductor as below:

 While for the EVM, it is recommend to use this inductor:

1)      EVM board and datasheet recommend inductor are different

2)      By referring to the EVM Inductor part number, it’s supposed to be in Metal Alloy Inductor appearance.

 

3)      But at the real EVM board, it is shielded chip coil part:

 

Can you kindly please help to confirm the part used in the development board?

Thanks,

Br,

    Hi Teach：
    There is a BOM list in the user's guide. If the EVM you use is latest TPS61099EVM-768, then the inductance should be: DFE252012P-2R2M=P2.

    And I checked with team that there was another version EVM. It used Wurth Elektronik 74404024022.
