Part Number: TPS54302

Hi Team,

 

Our customer would like to know the DCR of inductor which is used for the efficiency measurement at “VIN=24V, VOUT=3.3V” and “VIN=12V, VOUT3.3V”.

Could you please let us know if you have the parts number of inductor?

    Hi Kanemaru,

    We don't have the PN now, the original data hasn't been stored. The only thing we could confirm that the inductance for 3.3V output is 6.8uH, so the DCR of 6.8uH should be less than 10uH, that means the DCR of inductor for 3.3V output is a lltier lower than 23mohm. 

    Actually, the DCR of inductor makes no big difference here between 5V output and 3.3V output because the DCR would be no significant difference.

    BRs,
