TPS25762-Q1: TPS25762-Q1 base firmwave package.

Can you offer me your email address?

hi Ziv my email address:jianxi.cao@bshg.com. TKS.

Hi  Ziv,

I have a project use TPS25762 for PD output power supply design.

At present,  "FULL FLASH IMAGE" is generated through GUI configuration, the bin file is burned into EEPROM through I2C programmer and then welded to the board.

Then through the PD decoy test, TPS25762 can output 5V and 9V, but 12V, 15V and 20V can not output. PD decoy request 12V or higher voltage, but the output voltage has been jumping, 0V, 5V, 40V and so on.

PD decoy connected to other  PD chargers can normally output the required voltage.

I have uploaded my schematic diagram, please help to check the cause, thank you very much!

Hi Jianxi,

Schematic looks fine from my side. Can you send me the jason  configuration file?

Hi Ziv

enclosed configuration file and Vbus output wave picture, pls check.

Hi Jianxi,

What device do you use to decoy loads? 

hi Ziv

i use PD trigger as load for TPS25762.

PD trigger information as below. currently, PD triggger could communication with TPS25762, and TPS25762 can output 5V and 9V.

PD trigger's TaoBao link is: item.taobao.com/item.htm

hi Ziv,

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. picture as below, pls help to analyse, thank you in advance!

Will send one config to you by email.

Hi Ziv,

thanks for your config files.

i have try to use your full patch and jason configuration file. it seems doesn't work in my board,  it is same problem to my previous conifg.

CC1 and CC2 is changed with switcher, i upload schematic, pls check if CC design is not good.

thank you!

Hi Ziv,

my problem has already been settled and thank you sincerely for your valid support.Currently,i can get 5,9,12,15,20V output  but only get 4 outputs in one configuration.The configuration picture below ,pls check whether i can get 5 outputs in one configuration.
