Hi teams,
My customer wants to use Type-C supply 5V/3A to their product. So Could you give me TI solution to get 5V/3A?
Thanks!

Hi Jimmy,
UFPs, in general, can only detect what is advertised by the DFP and adjust the power consumption accordingly. UFPs are responsible for adjusting power consumption such that it lower than what is advertised. TUSB321 can detect 5V/3A advertisement from a DFP.
FYI, using a CC controller VBUS will always be 5V. USB PD is required to raise VBUS above 5V.
Hi team,
yes, I know.
My customer just use 5V to their product. My customer do some testing.( Use 5.1K pull CC1 and CC2 down ) ,can open bus 5V , but current is not enough 3A, just around 0.9A.
So how can get more current?
Hi,
For this kind of testing you will need to make sure CC1/2 voltage is above ~1.35V. Not sure what your pull-up voltage.
Hi teams,
thanks for your great reply.
I want to know if want to get 5V/3A from type-C adaptor. Does need any PD phy IC to get 3A ?or just setting CC1,CC2 5.1K pull low can get 3A capability.(If the adaptor can meet 5V/3A)
Thanks!
H Jimmy,
That's correct for 15W applications no PD is required. You can also use a USB-C analyzer to decode what is happening on the CC lines.
