TPS62175: TPS62175 inductor.

Part Number: TPS62175

Hi Team,

My customer is planning to use TPS62175 in one of the design and have below queries on usage of 6.8uH in the design,

  1. Please confirm whether 6.8uH inductor can use in the design?
  2. If so what will be the output C value for this inductance?
  3. Can you please simulate and let us know what will be the reduction in switching current with this C and L.

Regards, Shinu Mathew. 

  • Shinu,

    It is possible to use a 6.8uH inductor with a 22uF (or larger) output capacitor.

    Please refer to the Optimizing the TPS62175 Output Filter (SLVA543) application note for more information regarding the output LC's impact on loop stability, load transient behavior, and output ripple.

    Likewise to better confirm loop stability, you can use the models available here, and simulate a load transient with any different output LC combinations you are considering.


    Thank you,
