FP6298XR-G1 from Advanced Analog Technology, in a SOP-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	PGND	power_in	Power ground for the internal power MOSFET source. Tie directly to the ground plane with short, wide traces along with the input/output capacitor returns.
2	OC	input	Adjustable current-limit programming pin. A resistor of 26kΩ to 500kΩ from OC to GND sets peak switch current from 4.5A down to 0.5A per IOCP = 110000/R3 + 0.3. May be left floating for the default limit; do not add capacitance and keep the trace short.
3	VCC	power_in	IC power supply input, 2.6V to 5.5V (absolute maximum 6V). Bypass with a low-ESR ceramic capacitor placed as close to the pin as possible. Do not tie back to VOUT.
4	EN	input	Enable control input, active high. VEN >= 0.96V enables the converter; VEN <= 0.6V shuts it down (shutdown current 0.1µA typ). Absolute maximum 6V.
5	GND	power_in	Analog/signal ground reference for the IC. Connect to the ground plane together with PGND, CIN and COUT returns.
6	FB	input	Error-amplifier inverting input for output-voltage feedback. Regulated to VREF = 0.6V (±2%); output is set by VOUT = 0.6V x (1 + R1/R2). Route the divider directly to this pin and keep away from the LX switching node.
7	NC	unconnected	No connect. Leave floating or tie to GND only; do not connect to any other node.
8	LX	power_out	Switching node - drain of the internal 12V / 4.5A / 0.08Ω N-channel power MOSFET. Connect to the boost inductor and Schottky diode anode with short, wide traces to minimize EMI.
9	EP	power_in	Exposed thermal pad on the package bottom. Must be soldered to the PCB ground plane for both electrical ground and heat dissipation.

CAD (KiCad official)

Symbol: FP6298XR-G1

3D model: SOP-8-EP (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`fp6298xr-g1.step`	125 KB	You want the bare part, or you mark your own boards.
`fp6298xr-g1-etched.step`	2.4 MB	You want the part with `FP6298XR-G1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 577 faces against 152 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.
