Hello,

I am looking for a chip that supports qc 4.0 and pd 3.0. I came across your ic and I had a few questions. The spec sheet does not say the voltage and current configurations that the ic is capable of outputting. It does say a max voltage, however there is no indication of a max current. I was wondering if it was able to do these: 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3A, 20V/5A. Also, since I am kinda new to your line up, does the chip support a dc input?

For reference, here is the project I am working on:

Battery Power Bank

2 USB type C cables

3.7 v input @ 6 ish amps

Need:

Does it supply 100W? (20V/5A)

Does it support DC Input?

Can I use one ic for two receptacles?

As you may be able to tell, I am pretty new at this and I am trying my best to learn. I appreciate any help that would guide me to finishing this project.

What I have gathered thus far is I need a buck converter to boost my voltage, then I need to somehow connect it to the ic so it can output the correct power to an attached usbc receptacle. Do you recommend adding anything to this circuit?

I really appreciate any help and I am looking forward to learning more about this.

Hi,

Our chip is PD controller which manages the PD messages. The voltage and current limitation depends on the power circuit of your board including buck-boost. The USB Power Delivery Spec defines the maximun power capability is 100w,5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3A, 20V/5A can all be satisfied. So, our chip won't be the problem for realizing your design.

The recommended chip for power bank is CCG3PA:

It supports DC input. However, it only supports one Type-C port and one Type-A port, so you would need 2 chip if you want to realize two Type-C ports.

You can take a look at our application note:

And you should take a look at power delivery specification if you want some basic knowledge:

Thank you so much for the speedy reply. The customer service here is really off the charts. One follow up question though: what is the difference between this at ccg5 with support for two usb type C cables?

Hi,

The target product of CCG5 is notebook, PC and dock. We have a more mature solution for CCG3PA power bank. Develop power bank with CCG5 is much more difficult and could met unexpected problems. And CCG5 is more expensive.
