TPS53689: ACLL

Hailiang Zhang

Part Number: TPS53689

Hi Team，

When the TPS53689 ACLL is set to be less than 0.125, it cannot be stored to the NVM, that is, it will return to 0.125 when powered on again. However, no errors were reported during this process.
Is there a minimum value?

Hi Hailiang,

The datasheet recommends having higher than 0.3 mohms.

Hi Ryan，

Could you help point out where the datasheet recommends higher than 0.3 mohm? Thanks.

Hi Hailiang,

On page 8 of the datasheet it displays that the test accuracy for the AC loadline is between -5 and 5% when tested above 0.3 mOhms. The datasheet says the value can go from 0 to 8 mOhms, so maybe it is not the minimum, but where they tested their values.

Best,
Ryan
