TPS92511DDAR from Texas Instruments, in a SO-8-EP. 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	VCC	power_out	Internal regulator output, typically regulated to 5.4 V. Connect a capacitor larger than 1 µF between VCC and GND.
2	PGND	power_in	Power Ground. Must be connected to the GND pin for normal operation. The PGND and GND pins are not internally shorted.
3	IADJ	input	Average LED current setting. An external resistor R_IADJ connecting IADJ to ground programs the average LED current. IADJ pin voltage is typically 1.25 V.
4	GND	power_in	Analog Signal Ground.
5	FS	input	Switching frequency setting. An external resistor R_FS connecting FS to ground programs the switching frequency from 50 kHz to 500 kHz (e.g. 500 kHz typical at R_FS = 20 kΩ).
6	DIM	input	PWM Dimming Control. Apply a logic-level PWM signal to dim the LED string. Internally pulled up. Upper threshold typ 1.0 V, lower threshold typ 0.44 V.
7	LX	output	Integrated MOSFET drain. Internally connected to the drain of the integrated low-side N-channel MOSFET. Connect to the output inductor and anode of the Schottky diode. R_DS(on) typ 1.4 Ω.
8	VIN	power_in	Input voltage supply pin to the device. Input voltage range 4.5 V to 65 V (67 V transient).
9	Thermal Pad	power_in	Thermal connection pad. Connect to a ground plane for heat dissipation.

CAD (KiCad official)

3D model: SO-8-EP (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps92511ddar.step`	123 KB	You want the bare part, or you mark your own boards.
`tps92511ddar-etched.step`	2.3 MB	You want the part with `TPS92511DDAR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 581 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.
