TPS62736: How to design resistance when 'VIN_OK_SET' is disabled?

Seungho Yu

Part Number: TPS62736

Hello,

I'm making the converter for energy harvesting with the device TPS62736 above.

I would like to ask how to design resistance of R1, R2 when I don't need to use the function 'VIN_OK_SET'.

I have already checked that 'VIN_OK_SET' is disabled by pulling the pin to VIN. But there's no information about the resistance(R1, R2) but about R3, R4 in this case.

Is it okay to just disconnect the resistor R1, R2 when 'VIN_OK_SET' is disabled?

Thank you.

Regards,

Seungho Yu

I think there's an error with the image I attached.

I reattach the images here.

Hi,

As specified in the datasheet, if you want to disable VIN_OK, tie the VIN_OK_SET pin to VIN. In that case, resistors R1 and R2 are not required.

I hope I answered your question. If you do not have further questions, I will close this thread.
