Other Parts Discussed in Thread: TPS2583XAQ1EVM-147
Tool/software:
Dear TI experts,
I've been debugging the TPS25830AQWRHBRQ1 customer board recently. I found the VBUS output voltage only reach 0.9V.
The design is reference the TPS2583XAQ1EVM-147.
The chip SW only have 0.9V fixed voltage level, no PWN switch signal.
The voltage input is 24V, EN pin voltage is same with EVM 11.9V.
The LS_GD is 0V.
RT set 49.9K, IMON/ILIMIT 5.62K.
CC2 connect 5.1K to GND，CC1 is open. CC1:4.14V CC2:0.4V.
CTRL1 and CTRL2 is set to 3.3V and test /FAULT/ /LD and /POL all 3.3V(these pin use the board 3.3V digital power, the chip VCC not be used).I am not sure whether it may meet sequence issue.
Can you give some suggestions on how to debug it, look forward your reply, Thanks a lot.
