STI9287C from TMI, 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 connected to inductor; maximum voltage rating 35V per absolute maximum ratings. |
| 2 | GND | power_in | Ground reference pin. |
| 3 | FB | input | Output voltage feedback input; high impedance node sensitive to noise requiring close placement to IC per layout guidelines. |
| 4 | EN | input | Chip enable/disable control input; drive above 1.5V to enable, below 0.4V to disable; supports PWM dimming at 1kHz to 200kHz; do not leave floating. |
| 5 | OVP | input | Over-voltage protection input monitoring output voltage for open circuit protection; 30V typical threshold with 2.5V hysteresis. |
| 6 | IN | power_in | Power supply input with operating range 2.5V to 5.5V; requires 1µF or greater ceramic capacitor decoupling to GND. |
