# FP6298XR-G1

**Advanced Analog Technology** · DC-DC Converters · SOP-8-EP

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`
- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.29x3mm`
- 3D model: SOP-8-EP (KiCad packages3D, STEP)
- 3D model files: `fp6298xr-g1-etched.step` / `fp6298xr-g1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `fp6298xr-g1.step` / `fp6298xr-g1.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`fp6298xr-g1.step`](fp6298xr-g1.step) | 125 KB | You want the bare part, or you mark your own boards. |
| [`fp6298xr-g1-etched.step`](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.
