FR9206S9 from FITIPOWER, in a TSOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground pin. |
| 2 | LX | passive | Power switching node to which the external inductor is connected, absolute maximum -0.3V to (VIN+0.3V). |
| 3 | VIN | power_in | Power supply input pin for 4.5V to 18V operation, with input capacitors placed as close as possible from VIN to GND to avoid noise influence. |
| 4 | FB | input | Voltage feedback input connected to VOUT through a resistive divider, regulated at 0.768V. |
| 5 | SHDN | input | Enable input pin: pull high (above 1.5V) to turn on the IC and low (below 0.5V) to turn it off, or connect to VIN with a 100kΩ resistor for self-startup. |
| 6 | BST | passive | High-side gate drive boost pin requiring a 100nF~1μF capacitor from this pin to LX to fully turn on the internal high-side NMOS. |
