TPS54560DDAR from Texas Instruments, in a SOIC-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	BOOT	passive	Bootstrap capacitor node for high-side MOSFET gate drive. A bootstrap capacitor is required between BOOT and SW; if the voltage on this capacitor falls below the minimum required to operate the high-side MOSFET, the output is switched off until the capacitor is refreshed. BOOT-SW absolute maximum is 8 V.
2	VIN	power_in	Input supply voltage with 4.5 V to 60 V operating range (absolute maximum 65 V). Provides power to the internal high-side MOSFET and control circuitry.
3	EN	input	Enable input with internal pull-up current source (~1.2 µA). Pull below 1.2 V to disable; float to enable. Can be used with two resistors to program input undervoltage lockout. Absolute maximum 8.4 V.
4	RT/CLK	bidirectional	Resistor Timing and External Clock input. An internal amplifier holds this terminal at a fixed voltage when using an external resistor to ground to set the switching frequency (100 kHz to 2.5 MHz). If pulled above the PLL upper threshold, the terminal becomes a synchronization clock input (160 kHz to 2.3 MHz). Absolute maximum 3.6 V.
5	FB	input	Inverting input of the transconductance (gm) error amplifier. Regulates to the internal 0.8 V reference. Absolute maximum 3 V.
6	COMP	output	Error amplifier output and input to the output switch current (PWM) comparator. Connect frequency compensation components (Type-II RC network) between COMP and GND. Absolute maximum 3 V.
7	GND	power_in	Device ground reference. Must be connected to the exposed thermal pad on the PCB for proper operation.
8	SW	power_out	Source of the internal high-side power MOSFET and switching node of the converter. Connect to the output inductor and catch (Schottky) diode. Absolute maximum -0.6 V to 65 V (-2 V for 10 ns transients).
9	Thermal Pad	power_in	Exposed thermal pad on the bottom of the package. Must be electrically connected to the GND terminal on the PCB and to a copper heat-sinking area for proper thermal and electrical operation.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps54560ddar.step`	123 KB	You want the bare part, or you mark your own boards.
`tps54560ddar-etched.step`	2.5 MB	You want the part with `TPS54560DDAR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 620 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.
