TPS62060: Any concern on Low value of feedback resistors

Motoyasu Hattori

Part Number: TPS62060

Hi,

According to TPS62060 datasheet P. 11, "To minimize the current through the feedback divider network, R2 should be within the range of 120 kΩ to 360 kΩ. The sum of R1 and R2 should not exceed ~1 MΩ, to keep the network robust against noise."

If R2 is less than 120kohm, Please let us know what is concern.

Thanks and best regards,
M.HATTORI.

Hi Hattori,

When R2 is lower obviously there's an increase in current in the feedback loop and it is not desirable. Is there a specific reason to choose a lower value? May be if you could share more details on the application, it would be easier to understand.

In any case, I would strongly recommend to follow datasheet specifications.
