I have revived question from customer.
In the data sheet, the ripple voltage is specified by the output capacitor of TPS61175.
However, it seems that the calculation formula and the measured waveform are different.
When Vin 5.5V, Vout 13.0V, Iout 1A, SW 1.2MHz, Cout 47uF
In the calculation formula, the ripple voltage is about 10mV.
If you add the ESR component, it will be 15mV.
Please tell us about the difference between this calculation formula and measured value.
Best regards,
