Beagleboard Hardware XM - TPS65950 Temperature

Other Parts Discussed in Thread: TPS65950

Hi everybody! I have a problem with the PMU of my Beagleboard XM rev. C. When I connect the power by the OTG port, the TPS65950 gets extremely hot.

I don´t know if it's normal, but the temperature is above 50ºC, and when I touched it, it burned my finger :(

Did someone have this problem?

Please, can someone help me?

Thanks

This is the first time I hear this.

Please check your supply and GND resistance. There may be some problem with this board, I am not sure. Generally all boards are checked prior to shipping to customer.

Thanks Gandhar. I have the beagleboard and I plugged in my laptop (MacBook Pro, and the USB port are fine, i don't think that is the suply or GND) by USB port. The temperature got up to 50ºC because I unplugged it, otherwise I think that it would have reach higher temperature!! Is that normal?

Now I'll try with an external power source.

Thanks

Ariel

I asked the beagleboard designer. He told me that this is the normal behavior of the board. You can ask this question on beagleboard forum as well.

Thanks for your answer Gandhar!!

But the temperature is higher than 50 degree C and I'm worried about the components voltage!! Sounds like the TPS65950 is shorted.
I have requested an RMA.

Thank you so much!

Ariel
