TPS68470: Power output issue

Patrick Chen

Part Number: TPS68470

Hello,

Below is customer schematics. But the power output TPS68470 has no power output voltage now. What register we could configure to let output has voltage? or any setup sequence that can provide to customer. Thank you.

Hello Patrick,
Please do not post proprietary information (like customer schematics) to this forum. I will notify the TI-expert about your query, but will remove the thread, so no competitors of your customer can see their schematic.
Please RE-POST the query without customer information, so this can be taken offline (I'll help if you'd include your e-Mail-address.
Thanks a lot,
Frank

Hi Patrick,
I managed to remove the schematics only. No need to re-submit.
Best regards,

Hi Patrick,

If they have 3.3V on 3V3_SUS and 3V3_VDD rails, they should at least see 1.8V on IO_OUT by default.

The other regulators will need to be enabled individually. I would recommend referencing the EVM user's guide for how to enable each block.

Hello Rick

One more question,

Customer's rear camera use Sensor OV8858 , PMIC TPS68470 , APL platform , WIN10 OS. They use Apollo Lake (APL) platform but base on skycam (Skylake Camera) architecture .

Check with thier BIOS and need driver for TPS68470.

Do we have PMIC control Logic driver for TPS68470 in APL platform ? Thank you.

Hi Patrick,

Drivers are supported by Intel, so you may have to reach out to a local FAE or their forum for support. Searching online there are a few references to one being developed, but I'm not sure what limitations exist across platforms:
