AZ34063UMTR-G1 from Diodes Incorporated, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	Switch Collector	output	Internal switch transistor collector. Rated to 40V and 1.5A switch current; connect to inductor/load per topology.
2	Switch Emitter	output	Internal switch transistor emitter. Rated 40V (VPIN1=40V) and 1.5A; connect to load/return path per topology.
3	Timing Capacitor	passive	External timing capacitor (CT) sets the oscillator switching frequency (up to 180 kHz). Typical value ~470 pF for the application circuits shown.
4	GND	power_in	Ground pin for all internal circuits.
5	Comparator Inverting Input	input	Inverting input of the internal comparator; compared against the 1.25V internal reference. Connect to the feedback resistor divider from VOUT to set output voltage. Input range -0.3V to 40V.
6	VCC	power_in	Voltage supply pin. Recommended operating range 3V to 36V (absolute maximum 40V).
7	IPK Sense	input	Peak current sense input. Monitors the voltage drop across an external current-sense resistor (Rsc) to limit peak current through the internal switch.
8	Driver Collector	output	Voltage driver collector. Rated 40V and up to 100 mA driver current; typically tied to VCC through a resistor in step-up applications.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`az34063umtr-g1.step`	122 KB	You want the bare part, or you mark your own boards.
`az34063umtr-g1-etched.step`	2.7 MB	You want the part with `AZ34063UMTR-G1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 671 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
