A TPS 61161A boost converter for a table lamp I made for my balcony. Somehow works at 86% efficency. 0805 cap for scale.
PS: This particular layout of this buck converter is simply horrible. It won’t be good for a commercial product but it’s fine for a table lamp. For a commercial product use a solid ground layer and large pads and copper pours instead of traces for lower inductance and EMI.
I did a UDFN3020 package by hand a couple years ago and it was tough to do. Its definitely a “dont drink a bunch of coffee before you do this” kind of operation.

Damn, that looks impressive. What’s the pin pitch and trace width/clearance?
That’s awesome 😎. Next, i wanna see one of the X2SON packages from you ;D (I’m joking, but you have my kudos if you pull it off!)

These are pretty easy on a proper PCB, but can be frustrating as shit on one without any soldermask.
