SY8201ABC from Silergy Corp, in a SOT-23-6. 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 | BS | passive | Boot-strap pin supplying the high-side gate driver. Decouple this pin to LX with a 0.1uF ceramic capacitor to develop the bootstrap voltage above VIN that drives the top FET gate. |
| 2 | GND | power_in | Ground reference for the device. Also serves as the case position for θJC thermal measurement and should be tied to a solid ground plane with thermal vias for heat dissipation. |
| 3 | FB | input | Output feedback pin. Connect to the center tap of an external resistor divider from VOUT to set the output voltage per Vout = 0.6V × (1 + R1/R2). Internal reference is 0.6V ±2%. |
| 4 | EN | input | Enable control input. Pull high (VENH ≥ 1.5V) to turn the regulator on; pull low (VENL ≤ 0.4V) to shut it down. Do not float. Absolute maximum voltage is VIN + 0.3V. |
| 5 | IN | power_in | Power input pin (4.5V to 27V operating, 30V absolute maximum). Decouple this pin to GND with at least a 1uF ceramic capacitor placed close to the pin. |
| 6 | LX | power_out | Switching node / inductor pin. Connect to the external power inductor; the internal high-side and synchronous low-side FETs switch this node between IN and GND. Dynamic voltage rating is IN+3V to GND-4V for 50ns transients. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 482 faces against 117 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.
