STI9287C

TMI · LED Drivers · SOT-23-6

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.
