CN5208 from ShangHai Consonance Elec, in a SOIC-8. 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	VG	power_out	Internal voltage regulator output. Supplies power to the internal gate driver; connect a 100 nF ceramic capacitor between VG and VCC.
2	GND	power_in	Ground. Negative terminal of the input supply and reference for all internal circuits.
3	SHDN	input	Active-high shutdown input. Voltage above 2.2V (VIH) puts the part into low-current (7.5uA typ @ VCC=15V) shutdown; below 0.5V (VIL) returns to normal operation after ~13 ms delay. Do NOT drive between 0.5V and 2.2V - device state is undefined.
4	COM	passive	Frequency compensation input. External R-C network (typ. R3 with C3=10nF, plus optional C4) tied to this pin sets the closed-loop compensation zero for the error amplifier.
5	OUT	input	Output voltage sensing input. Monitors the converter output voltage (regulated internally to 5V ±1%) and is the connection point for the positive terminal of the output bypass capacitor. IOUT ~9 uA typ at VOUT=5V.
6	SW	input	Switching node sense pin. Connect to the drain of the external P-channel MOSFET / junction of the inductor and the cathode of the freewheeling diode. Voltage swings from one diode drop below GND up to VCC; used with VCC to sense inductor current (VILIM=120 mV typ).
7	VCC	power_in	Unregulated DC power supply input (4.8V to 32V operating; abs max 36V). Powers the CN5208 internal circuitry and is the current-sense reference for SW. Bypass with a low-ESR ceramic capacitor.
8	DRV	output	Gate drive output for the external P-channel MOSFET. Push-pull driver with an internal clamp limiting swing to ~8V below VCC (typ 6V peak-to-peak); tr/tf ~40 ns into a 2 nF load. VDRV low (VCC-VDRV) up to 6.3V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cn5208.step`	122 KB	You want the bare part, or you mark your own boards.
`cn5208-etched.step`	1.7 MB	You want the part with `CN5208` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 409 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.
