Dear all.

There isn't a value of VOUT of PWM mode(VPS/SYNC = VIN) in the datasheet about TPS63061.
Is this +/- 1%?

And these value are TA=25°C.
Do you have "Operating free air temperature range" data?

Regards,

Yes, the accuracy of the adjustable version can be scaled up to the output voltage and is therefore +/-1%

TA = 25°C is valid for the typical numbers.
Min/Max values are valid over the recommended temperature range.

Our customer will use this device input 5V +/- 10%.
How much is the output voltage accuracy of TPS61061 in -40℃ to 85℃?
5V +/- ?? %
For example, do you have data of "Figure 22. Output Voltage vs Output Current" at -40℃ to 85℃?

The variation is +/- 1% which will end up in a 4.95V to 5.05V for PS/SYNC = VIN

Our customer measured by their board. (at 25dc)
I send to you a result.

Thanks for the schematic.
We discussed the accuracy with Power safe mode = disabled. In this circuit, the device operates in power safe mode and has therefore a different accuracy.
Please see datasheet page 5.
