FP6296XR-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 | LX | output | Power switch output. Drain of the internal 15 mΩ / 14 V / 10 A N-channel power MOSFET; connects to the boost inductor and Schottky diode anode. Pin 1 and pin 2 are tied together internally for higher current-carrying capability. |
| 2 | LX | output | Power switch output. Second LX pin bonded to the same internal MOSFET drain as pin 1; must be connected together on the PCB to carry the 10 A switch current. |
| 3 | Vcc | power_in | Power supply for the internal control circuitry and gate drivers. Regulated to ~5 V (4.75-5.25 V) internally from HVDD when HVDD = 12 V. Bypass to GND with a ceramic capacitor. |
| 4 | EN | input | Enable control input, active high. VEN ≥ 1.1 V enables the converter; VEN ≤ 0.6 V shuts it down (IDD ≤ 1 µA in shutdown). Do not leave floating. |
| 5 | FB | input | Error amplifier inverting input (feedback). Connect to a resistor divider from VOUT; regulates to the internal 1.2 V (±2%) reference (VREF = 1.176-1.224 V). |
| 6 | COMP | output | Loop compensation node. Error amplifier output; connect an R-C network to GND to stabilize the current-mode control loop. Sink/source capability ≈ 45 µA. |
| 7 | OC | input | Adjustable over-current limit programming pin. Connect a resistor (150 kΩ ↔ 51 kΩ) from OC to GND to set the peak current limit between 2 A and 10 A. Leaving this pin floating disables the adjustment (invalid); the default OCP is 10 A. |
| 8 | HVDD | power_in | IC power supply input, 2.7 V to 12 V (abs max 12 V). Provides bias for the internal LDO that generates VCC; also monitored by the UVLO circuit (VUVLO ≈ 2.2 V, 0.1 V hysteresis). |
| EP | GND | power_in | IC ground - exposed thermal pad on the bottom of the SOP-8L(EP) package. Must be soldered to the PCB ground plane for correct electrical operation and heat dissipation (θJC ≈ 10 °C/W, θJA ≈ 60 °C/W). |

## CAD (KiCad official)

- Symbol: `FP6296XR-G1`
- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.29x3mm`
- 3D model: SOP-8-EP (KiCad packages3D, STEP)
- 3D model files: `fp6296xr-g1-etched.step` / `fp6296xr-g1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `fp6296xr-g1.step` / `fp6296xr-g1.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`fp6296xr-g1.step`](fp6296xr-g1.step) | 125 KB | You want the bare part, or you mark your own boards. |
| [`fp6296xr-g1-etched.step`](fp6296xr-g1-etched.step) | 2.3 MB | You want the part with `FP6296XR-G1` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 562 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.
