HX1364A-AGN from HEXIN, in a SOP-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	FB	input	Feedback pin. Receives the divided output voltage from an external resistor divider (R2/R3) and is compared against the internal 1.20V reference. VOUT = 1.20V x [1 + (R2/R3)]. Feedback input current is ~0.05uA.
2	ILIM	bidirectional	Programmable current limit pin. Sources ~8.5uA (7-10uA) that develops a voltage across an external RLIM resistor to GND, setting the low-side switch valley current limit (RLIM(kOhm) ~= 45 x Imax(A)). Leaving ILIM floating gives a default current limit of 1.5A.
3	EN	input	ON/OFF control input. Drive above 4.0V to enable the part; drive below 1.5V to shut down the device. Do not leave floating. Absolute maximum voltage is 6V.
4	VIN	power_in	Main input supply pin. Operating range 8V to 38V (absolute maximum 40V; input protection mode trigger at 32V). Must be decoupled to GND with a 100uF or greater ceramic capacitor located close to the pin.
5	SW	output	Switch node. Connects to the external inductor. High-frequency switching node between the internal P-channel and N-channel MOSFETs; keep trace area small. Pins 5 and 6 are tied internally and both must be connected to the inductor.
6	SW	output	Switch node. Connects to the external inductor. Second SW pin, internally tied to pin 5; both should be connected in parallel to reduce trace resistance.
7	GND	power_in	Ground return pin. Pins 7 and 8 are the device ground and should both be connected to the PCB ground plane; analog grounds should join at a common node and connect to power ground behind the output capacitors.
8	GND	power_in	Ground return pin. Second GND pin, internally tied to pin 7; both should be connected in parallel to the ground plane for reduced impedance and improved thermal dissipation.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`hx1364a-agn.step`	122 KB	You want the bare part, or you mark your own boards.
`hx1364a-agn-etched.step`	1.9 MB	You want the part with `HX1364A-AGN` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 490 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.
