MFP6291LR-G1 from MSKSEMI, 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 | SW | output | Power switch output. Drain of the internal N-channel MOSFET (80 mΩ RDS(on), 2.5 A typical current limit). Connect the boost inductor and the anode of the output rectifier here. The SW node swings between GND and up to 22 V. |
| 2 | GND | power_in | Device ground. Tie to a strong ground plane for heat sinking and noise return of the switching currents. |
| 3 | FB | input | Feedback input to the internal error amplifier. Regulates to VFB = 0.6 V (0.588 V min / 0.612 V max). Connect an R1/R2 resistor divider from VOUT to FB to GND to set the output voltage: VOUT = 0.6 V × (1 + R1/R2). |
| 4 | EN | input | Regulator enable / on-off control. VIH ≥ 1.5 V turns the converter on; VIL ≤ 0.6 V shuts it down (IQ ≈ 0.1 µA). Tie to VIN for automatic startup; do not leave floating. |
| 5 | VIN | power_in | Input supply pin, 2.2 V to 16 V operating range (18 V absolute max). UVLO releases at ~2.2 V with 100 mV hysteresis. Bypass locally with a 22 µF X5R/X7R ceramic capacitor placed close to the pin. |
| 6 | OC | input | Adjustable peak-switch current-limit programming pin. Connect a resistor (R3) from OC to GND, 19 kΩ to 96 kΩ, to set IOCP = 48000 / R3 (0.5 A to 2.5 A). If left floating, the internal 2.5 A current limit is used. |
