Advanced Analog Technology · DC-DC Converters · SOP-8-EP
FP6276BXR-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 | power_out | Power switch output. Internal drain of the low-side NMOS and source of the high-side PMOS; connect to the boost inductor. Absolute max 6V. |
| 2 | LX | power_out | Power switch output. Second LX pin, tied internally to pin 1. Connect to the boost inductor switching node. |
| 3 | VIN | power_in | IC power supply input. Operating range 2.4V-4.5V (abs max 6V). Decouple locally to GND. |
| 4 | EN | input | Enable control, active high. VEN >= 0.96V enables the converter; VEN <= 0.6V shuts it down (shutdown current <1μA). Abs max 6V. |
| 5 | GND | power_in | IC signal ground. Reference for the internal analog circuitry. Must be tied to the exposed pad (PGND) at the device. |
| 6 | FB | input | Error amplifier inverting input. Connect to the mid-point of the VOUT feedback divider; regulated to VREF = 0.6V (±2%). Abs max 6V. |
| 7 | OC | input | Adjustable current-limit programming pin (floating available). A resistor to GND sets the internal switch current limit (default typ. 6A); leave floating to use the internal default. Abs max 6V. |
| 8 | VO | power_in | Output voltage sense pin. Connect to the boost output rail; used internally to power the high-side driver bulk-well switch via a VO/VIN MUX. Abs max 6V. |
| EP | PGND | power_in | Exposed thermal pad and IC power ground. Must be soldered to the PCB ground plane and connected to GND (pin 5) for proper operation and heat dissipation. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 507 faces against 63 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.
