LMR16006YDDCR from Texas Instruments, in a SOT-23-6. 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	CB	input	Bootstrap capacitor pin. Switch FET gate bias voltage. Connect a Cboot capacitor between CB and SW; recommended CB-to-SW voltage 0 to 6 V (abs max 7 V).
2	GND	power_in	Ground connection for the device. Reference for internal control circuitry and return for VIN and SW currents.
3	FB	input	Feedback input pin. Set the output voltage using a resistor divider from VOUT to FB, VOUT = VFB * (1 + R1/R2), where VFB is typically 0.765 V (0.747 V to 0.782 V). Absolute max 7 V; recommended 0 to 5.5 V.
4	SHDN	input	Active-low enable/shutdown input, high-voltage tolerant (abs max 65 V). Has an internal pull-up current source; pull below 1.25 V (typ) to disable, float to enable. Can establish input undervoltage lockout with a two-resistor divider.
5	VIN	power_in	Power input voltage pin. Input for internal supply and drain node of the internal high-side MOSFET. Operating range 4 V to 60 V (abs max 65 V). Bypass with a low-ESR ceramic capacitor placed close to the pin.
6	SW	output	Switch node output. Source of the internal high-side MOSFET; connect to the inductor, the catch (Schottky) diode, and the bootstrap Cboot capacitor. Recommended -0.3 V to 60 V; supports up to 600 mA output current with 1.2 A typ peak current limit.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmr16006yddcr.step`	97 KB	You want the bare part, or you mark your own boards.
`lmr16006yddcr-etched.step`	2.4 MB	You want the part with `LMR16006YDDCR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 597 faces against 117 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.
