TPS62869EVM-118: Unable to open GUI link to program the TPS62869EVM-118

Hello Rama,

you are correct, the link to the GUI is missing. I will contact the responsible engineers to update the pages and provide the link. I will come back to you next week.

Hi Werner,

Thank you the reply.

one more query regarding the part "TPS628680A", For this part the start-up output voltage and device I2C target address are set by an external resistor connected to the VSET/VID pin and after start-up the output voltage can be changed using I2C by keeping VID pin either low=Vout1 or High=Vout2 . So in GUI after setting Vout1 or Vout2 to required output voltage and then writing to register(Using WRITE REGISTER in GUI) holds the value permanently or it will disappear after power cycling?

1)Please confirm does the register values retained after power cycling?

2) what is purpose of IMMEDIATE WRITE ?

Hi Werner,

we would like to do voltage margining from 0.2V to 0.875V , In this Case this TPS628680A part wont help us as we have to set  start-up voltage through external resistor every time.

Any VR's available with below requirements?

VIN= 2.4V to 5.5V

VOUT=0.2 to 0.875V

Output Current =3 to 4Amps

I2C feature must for voltage margining from 0.2 TO 0.875V(Note: I2C registers must retain the configured value after power cycling)

Power Good Indicator pin must.

Thanks.

Hi Rama,

unfortunately, we do not have devices that retain register information after power cycles.

The only device that support Vout down to 0.2V is the TPS62868 family that you already mentioned.

Hi Werner,

We are using TPS628680A part for 0.5V generation, In one application this TPS628680A output circuit will get connected to 0.5V which is generated from other source. so at that time we are disconnecting INPUT & ENABLE to stop the generation from TPS628680A part, so please confirm does this TPS628680A has reverse current protection or is it okay to have 0.5V output from other source when TPS628680A is disabled ?

Thanks.

Hi Werner, GUI link is still not working. Could you please look into this?

Here you go:

Hi Werner , we are facing issue while installing the GUI from the link which you have shared, first we tried installing from web and got below error and second time tried by installing from file and unable to give correct path for installation as we have multiple files. Please share if any installation guide doc available

Thanks.

Hi Werner,

To test the TPS62869EVM-118 module, USB TO ANY  dongle is used in user guide, Is it possible to connect to the GUI through aardvark dongle?

Hi Rama,

the installation works on my network, please check with a different internet connection or your IT department, if they are blocking something.

The GUI only works with USB to ANY adapter.

Regards, Werner

Ok, But for changing the output register values.can we use Total phase control center tool with aardvark dongle or it is possible with any adaptor to change register values?

Hi Werner,

is it possible to change the output register values using any adaptor?

Thanks

Hi Rama,

yes, you can use any I2C controller to change the registers. Please follow the commands as described in the datasheet.

Regards, Werner
