TPS552882-Q1: Inductor selection

Part Number: TPS552882-Q1

Hi 

My customer application condition as below, can you help recommend the inductor spec for below conditions ? thanks!

Vin = 5.5 V ~ 19 V

Vout = 9.2V, 5A 

Switching frequency = 400KHz 

  • Hi PY,

    Please refer to Chapter 8.2.2.4 in Datasheet for inductor selection, the main specifications that need to be considered are: inductance, saturation current and DCR.

    Recommend to choose a inductor with 4.7uH or 6.8uH, Isat>10A.

    Regards,

    Bryce
