Part Number: TIDA-00882
Hi team,
Just wanted to confirm, this reference design was tested with ECS-400-20-33 as crystal, correct?

Part Number: TIDA-00882
Hi Team,
This is customer request, can you please advise:
"
There are very large capacitors and an inductor on the evaluation board. The design we will make must fit into a very narrow space. This is probably related to the DC-DC converters used, but could we ask you to use smaller surface mounted tantalum capacitors instead of these large capacitors?
"
Thanks in advance

Hello
is it possible to get the config file of the TPS65982 used in the TIDA-00882.
Thank you

Part Number: TUSB9261
Hi,
After taking a look at the TIDA-00882 several questions on the TUSB9261 have come up:
1) Reference Design's I2C Interface: GPIO0, GPIO6, and GPIO1 are being used as an I2C interface between the TUSB9261 and the PMIC, TPS65982. Looks like the TUSB9261 is the bus master. We are not using this interface. I am assuming that we do not need to use this interface, and the TUSB9261 will work fine without any other device hanging off of it. Regardless, do we need to add pullups to GPIO0 (SDA), GPIO6 (IRQ1Z) , and GPIO1 (SCL)? Right now we have these pins unconnected and floating.
2) Reference Design's GPIO4, JACK_DETECT: I have seen some other documentation for this pin. It appears it is configured as an input pin to tell the TUSB9261 that it is being supplied by an External Supply, and not from the USB Cable. What is the proper use of this pin? How does the TUSB9261 operate differently on External or USB cable power? We have left the pin floating. I am assuming we should pull it high or low. Any advice?
3) Reference Design's GPIO10, SATA_EN: This is an output pin to control the power to the SATA HDD device. On our board, I never see this pin move. It is always high. We have a pull-up on this pin, so I don't know if it is being driven or floated by the TUSB9261. Does the Firmware really do anything with this pin?
4) Reference Design's GPIO11, FAULT#: This is configured as an input pin that is driven low when SATA HDD device (and TUSB9261) is exceeds a current limit setting. We have left this pin floating. Is this ok, or should we add a pull-up?
5) Regarding remaining GPIO Pins, GPIO2, GPIO3, GPIO5, and GPIO7. On the reference design, they all are effectively left unconnected/floating. Even though at least one of them, GPIO5 appears to configured as an input. Is it ok to leave them all of them floating, or should we add some pull-ups or pull-downs?
6) Regarding the USB interfaces. We are only using the USB 2.0 interface. We are not using the USB 3.0 connections. I just want to confirm that it is ok to leave the 4 USB.3.0 pins floating.

Hi Atiq,
Thanks for your reply.
I got GPIO mappings for TIDA-00882. Actually, it can be found on schematic. I need the TPS65982 config file used in TIDA-00882. Please help to provide if it is available.
Thanks.

Part Number: TIDA-010081
Hi All,
I tried TIDA-010081 layout and with same components suggested by TI, except Transformer and inductor due to non- availability. It is working fine with TI PCB layout. I am getting 54VDC output.
Now I have changed PCB layout, with minor modification only at Transformer and inductors, to suit our ETD-49 transformer footprint.
Up to PFC it is working fine. I am getting 384VDC at PFC output.
But Final output, i.e., 54V is not coming properly. It starts at 36VDC and then slowly increasing upto 42VDC only.
What could be the problem? Is it output side or input side? I am not able to understand the issue.
If it is layout issue, where would be the problem for this kind of symptom? Please suggest and help me.
