LP8866-Q1: Question about R_isense and R_sense

Part Number: LP8866-Q1

Tool/software:

Dear TI experts,

My customer tests LP8866-Q1 for their new project.

And they have questions about the values of R_isense and R_sense resistors.

1) About R_isense, It is recommended as 0.02ohm in EVM schematic. (R3)

But my customer have enough stock of 0.05ohm resistor.

In the equation 19 on page 36, it shows 2 more variants except R_isense. (I_vin_ocp and VIN_ocp_th)

So I cannot expect the result if I change 0.02ohm to 0.05ohm.

Could you check that what would be happen If I change R_isense from 0.02ohm to 0.05ohm?

2) Same idea as no.1.

About R_sense, it is also recommended as 0.02ohm in EVM schematic. (R15)

Could you also check that what would be happen If I change R_sense from 0.02ohm to 0.05ohm?

Please check these issues. Thanks.

Best regards,

Chase
