Hi,

 

I need an easy to use IC that can provide 15V@3A through USB type C. I found the STMicro STUSB4500 IC, which looks perfect but it seems limited to 30W max. Anyone have suggestions?

Are you looking for something that can provide 15v 3A through a USB C cable, or are you looking for something you plug into your computer and produce 15V 3A?? If so that's 45W, and I believe a USB 3.0 port will only put out 5W max if I remember correctly.

This is USB type C which is rated for upto 100W at multiple voltages. I need an IC that can talk to the power delivery IC at the other end of the usb cable.

TY,

 

Being a heavy user of Cypress PSOC 1 uCs, I really should have looked at Cypress. The internet saves the day again.

Well, although that it may be not related but I suppose you are using a Li-ion battery, in that case you can use a Li-ion battery charger IC and it will take care of that. check Richtek they have some options...
