Hey @wagiminator :)
I decided to use the usb-c part of your design into my 6V-2A boost project.
I discussed on reddit the pcb, and someone linked a very interesting doc about usb-c power negotiation.
https://forum.digikey.com/t/simple-way-to-use-usb-type-c-to-get-5v-at-up-to-3a-15w/7016
It seems that hooking the usb-c with the two simple 5k1 resistors doesn't comply with proper usb-c power negotiation and will instantly try to draw 3A, even if the power delivery doesn't supports it. Have you experienced some related issues? Have you considered this ? :)
Cheers!
@4e131906 Hi,
"An upstream facing port must connect a valid Rp pull-down resistor to GND (or optionally, a voltage clamp) to both CC1
and CC2 pins. A 5.1kΩ ± 10% is the only acceptable resistor if USB Type-C charging of [email protected] or [email protected] is to be
used." The IP5306 draws the current it needs, which is always less than 3A. Of course you have to choose a power supply which is capable of delivering min [email protected]! I've tested the charger with different power supplies and they all worked.
Greetings
Thank you very much Stefan :)
