Hello, This has been racking my brain all day and im starting to get frustrated!. I'm trying to fix an Acer Laptop that has a 260c short on a component marked L8=7B B4H, from research im pretty confident its a monolithic power system IC but i cannot figure out the model or if im even right in assuming that. Thanks for the help in advance.

Is there a place i could find this step down converter? I've tried mouser and digikey neither of which have it. i also made an account on the richtek website and they've claimed to have sent me an email link to validate my account but i have not received anything.Comment

Hi.
Could somebody help me to identify component with marking code TV6VD?

Input voltage is 19V.
