Hi All,

I want to design a mobile charger with USB-C. I was checking reference designs and application notes but wasn't able to find one. Can anyone please help me with this.

@QDrives please check if following documents are fine for the study or not?
I found these 2 documents which I think fit for the study.

Seems complete.
Do note that they are mains powered. Mains power can kill you.

Ok. Thanks.

If I want to design it with PMIC then what I can do?
Design Requirenment-
Vin= 220VAC
Vout= 5V
Iout- 1A
Power 5W or 10W

I dig a little bit on google and found the following circuit. Pls suggest.

Why I want in PMIC is because I tried the above design and found the ICs U1 and U2 is obselte and didn't found any alternate and when I discussed with my mentor then he said design with PMIC. So I am trying to find any IC or reference circuit which will help me to fulfil my requirenment. I am searching online right now as well. But it will be helpful if you will help parallely so it will make my work easier.

Did you also check this: https://webench.ti.com/power-designer/switching-regulator?powerSupply=1
And I would do isolated.

Yes, I tried this but simulation is not available for the circuit so I am not able to validate whether the circuit is correct or not.

Same problem. Nothing is here.

QDrives , 03-07-2025, 05:00 PM

What do you mean "nothing is here"? Power Integrations has plenty of AC to DC power solutions.

Basically I tried but didnt find anything which will help me.. or maybe I searched wrong. I am still exploring the site. I will let you know if I didnt get anything. I also find some circuits in webench. They have report attaching like output is 5V 1A etc. but nothing is like with PMIC. Still exploring. I will let you know if I need more help.
