I've long been wondering what ICs are used on these 60W USB PD supply boards as the markings have always been lasered off.
Now I saw one with the marking still on and the IC is available on LCSC! https://www.lcsc.com/product-detail/C42460907.html
Wild that you can get a 60W DC/DC converter in a 4×4mm QFN16 package for 60ct.
