TX-SDK-V2 EVM Power problem at banana connector cable

Hello Subash,

Your issue with the TX-SDK-V2 may be related to the LM96570 power supply sequencing. According to page 13 of the user's guide (copied below), the 3.3V supply should be powered up before powering the 1.8V supply:

Can you please verify this sequence and report back if this resolves your issue?

I follow the power sequence order such as Vsub,3.3V and 1.8V order only.

Could you see this post e2e.ti.com/.../542675 It is an other issue related to registers of lm96570 IC

When i am measuring the voltage of 1.8V pin with respect to gnd pin, it always gives 1.4V. But when i am measuring the voltage with respect to power supply gnd pin, it shows 1.8V. Do you have any idea?

Hello,

The only thing we can think of is if you have a large amount of current that is causing the voltage drop.

What kind of current readings are you getting on your power supply?

Are you sure the banana cables / connectors are low impedance and you are getting a good connection?

Yes, In TX-SDK-V2 board, short circuit is there betwee ground and 1.8V pins. And the lm96550 pulser IC's gold color is turned into white color. Why?

Hi Subash,
I just replied to your other post on this as well:
