Hi Liguidong,
Unfortunately our team does not have experience with this device since it was developed more than 15 years ago by a different team.
I don't know if the Linux drivers located here might be of help: https://www.ti.com/product/TPS65950#software…
Part Number: TPS65950 I found a tolerance for the prescaler on the VBAT of 20% (table 5-70 in the TPS65950 datasheet, specifies 0.2~0.3V/V).
This tolerance is extremely wide, but I also can’t find a tolerance for any of the other ADCs (I specifically…

Part Number: TPS65950 Other Parts Discussed in Thread: DM3730 I'm looking at the PCB layout guide for the TPS65950 (document swcu055a), and in Figure 3 I see a recommended scheme for pads with a trace between them, including a pad diameter of 220 um.…
Part Number: TPS65950 Hello,
In the TPS65950 Layout Guide (swcu055a), Figure 7 shows a recommended placement. I can't find a schematic or BOM to accompany that placement, so the reference designators shown aren't very meaningful. Are those docs…
Part Number: TPS65950 We are not using any analog audio inputs in our TPS65950-based design; we're only taking in I2S data and using the headset amplifier output. The schematic checklist says to leave unused inputs such as microphone inputs "floating…
