TPS61194-Q1: LED could not work normally，and fault showed the sch of LED is open

Vidhya Jeyapaul

Part Number: TPS61194-Q1

Hi Team,

I am confused with this T-resistor network calculation.

Which one to follow? Attached Excel calculation or attached snap.

If I try same resistor values from snap in the resistor calculation excel, Vboost value calculated is different and not 20V or 30V or 40V.

Kindly revert asap.

Thanks and Regards,

Hi,

Where did you get this datasheet snap of TPS61194-Q1? I do not see any problems here. And would you please attach the excel calculator again? I cannot see it. Thanks.

Hi,

I tried using the resistor values from the snap to calculate in the excel calculator, and get the same results as 20V, 30V, 40V. I do not see any problems. Would you mind check again?
