KP1062SPA 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	COMP	input	Constant-current output loop compensation pin. Recommended to connect a 1-4.7 µF ceramic capacitor to GND. Internal clamps: Vcomp_H = 3 V (high), Vcomp_L = 0.7 V (low).
2	GND	power_in	Chip reference ground.
3	VDD	power_in	Chip supply pin. Normal operating voltage 10-13 V (typ 11.5 V); UVLO ~8 V; clamp 14 V @ 5 mA. Recommended bypass ≥ 2.2 µF ceramic capacitor to GND.
4	FB	input	Inductor current demagnetization detection and output over-voltage protection pin. Demag threshold VFB_DEM = 0.2 V; OVP threshold VFB_OVP = 2 V (typ).
5	Drain	passive	Internal 650V power MOSFET drain input pin (tied with pin 6). Also serves as HV startup/supply source (IHV = 10 mA @ Drain = 20 V). Rdson (KP1062) = 4.5 Ω.
6	Drain	passive	Internal 650V power MOSFET drain input pin (tied with pin 5). Rdson (KP1062) = 4.5 Ω; VBR = 650 V.
7	CS	input	Current sense input pin. Peak current reference Vcs(max) = 1.5 V (typ); constant-current output reference VCC_REF = 200 mV (typ); leading-edge blanking TLEB = 300 ns.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`kp1062spa.step`	111 KB	You want the bare part, or you mark your own boards.
`kp1062spa-etched.step`	1.9 MB	You want the part with `KP1062SPA` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 481 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.
