TPS25762-Q1: TPS25762 application issure

Dear TI support team,

I have a project which use TPS25762 for PD charging.

1. In order to get the availableoutputs of the chip,i use PD trigger as load,but only 5V and 9V is stable,other higher voltage request causes outputs jumping.
2. Additionally,I have another try.i connect TPS25762 to notebook  which supports PD charge with standard TypeC cable. then i use the oscilloscope to capture the wave of the TPS25762's output.
3. Configuration keys files and base firmware areget from TI E2E teams.
4. I have uploaded my schematic diagram, Vbus output pictures,PD triggerinformation and Configuration files

Pls help to double check my design and analyse why PD Vbus can’t output 12V/15V and so on.

Thank you in advance!

Hi

    建议你将这个问题放到美国E2E上：  https://e2e.ti.com/

    TI这边关于 TPS25762的资料相对较少，主要是没有程序之类，在美国E2E上问一下是否有例程提供。
