Hi,

Did you try to capture data with the EVM?

thank you

Hello User,

and the output voltage of TPS43351 is abnormal

What do you mean by the above statement? What is the abnormality you're observing?

Also, can you clearly let us know what all LEDs glow when you supply power to the device? And what is the rating of the power supply used in this case?

Regards,

Hi 

When powering the device, all the LEDs glow, but the location of the light does not match the data sheet.

V The measured power supply is about 1.5V(test point TP44, i.e. the side of inductance L29)

Hello User,

We have identified a problem which may effect a small number of these boards. We found out that the initial power inductor on the rail seemed to be very close to out of spec for what is recommended. 

I would recommend returning and replacing this unit.
