Hello ,Same problem here but mine its an tuf 1660 super with diferent chips ,they say AEAM 119 , by googling it, i found symylar Synchronous Buck Converters that are produced by Alpha-Omega, maybe this are too . but by the code i cant find. on pinout apear be exactly the same as RT6220.
The pex voltage it's down and i reflow ,work until i shutdown ,so the GPU it's good ,i s just the buck converter dead.



i have no ideas where to find this
