Hi Jeff,
Any possibility to find this?
Labeled -
2W=3A
J3U

According to this website, it is a PWM Controller

Sorry, I cant identify who is making this one.
Did more searching late last night and I think it’s Richtek but had no luck searching their website.
Thank you Jeff.

I thought it was them also, but do a search on their site here. You just have to add 2W next to “marking code” as show below. Their site brings up a different part with that marking. So, I figured it’s another company using a similar marking.
Thank you again for your time and effort Jeff.
Regards,
Rich
