Sure it is this chip. www.mouser.com/ProductDetail/595-TPS54335ADDAR You should be sure this is the problem first. it is possible that other components can fail that are further upstream of this one such as www.mouser.com/ProductDetail/512-FCD7N60TM and www.mouser.com/ProductDetail/595-UCC28630D
@@mickfixesjunk Thank you for that. I ordered the parts and ended up replacing the mosfet 3 times (comfortable with SMD rework now) before I realized I am now missing the blue "resistor" bottom left of U1401 (dead center in the video at ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bnGMT3WfVdM.html). Is that orderable too? would you know what resistance value?
