KP1192SPA from Kiwi Instruments, in a SOP-7. 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	ROVP	input	Output over-voltage protection setting pin and enable input. Connect a 5K~14K resistor to GND to adjust the output OVP threshold; open-circuit is equivalent to ROVP=14K. Also integrates enable function: when VROVP < 50mV (i.e. tied to GND), the chip is disabled. ROVP sources ~40uA typical.
2	GND	power_in	Chip reference ground.
3	NC	unconnected	Non-functional pin, leave floating in use.
4	HVDD	power_in	Chip high-voltage supply pin. HVDD start-up voltage typ 15.5V; shutdown voltage typ 8.0V (7.2V min, 9.5V max). Charge current capability ~10mA at Drain=20V. Absolute max 650V.
5	Drain	power_in	Internal power MOSFET drain input pin. 650V breakdown voltage. Rdson typ 4.4Ω for KP1192SPA. Pins 5 and 6 are internally tied to the MOSFET drain.
6	Drain	power_in	Internal power MOSFET drain input pin (paralleled with pin 5). 650V breakdown voltage. Rdson typ 4.4Ω for KP1192SPA.
7	CS	output	Internal power MOSFET source output and current-sense input. Peak current reference Vcs(max) = 600mV typ (590-610mV). Leading-edge blanking 500ns typ. Absolute max voltage -0.3V to 7V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`kp1192spa.step`	111 KB	You want the bare part, or you mark your own boards.
`kp1192spa-etched.step`	1.8 MB	You want the part with `KP1192SPA` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 451 faces against 132 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.
