STI3508C

TMI · DC-DC Converters · SOT-23-6

STI3508C from TMI, in a SOT-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 LX output Power switch output and drain of the internal MOSFET switch; connect the power inductor and output rectifier to LX, which has an absolute maximum rating of 35 V.
2 GND power_in Ground pin.
3 FB input Feedback input regulated to 0.6 V for the STI3508C (1.2 V for the STI3508CA); connect the output resistor divider to FB, with an absolute maximum range of -0.3 V to 7 V.
4 EN input Regulator on/off control where a high input (at least 1.5 V) turns the converter on and a low input (at most 0.3 V) turns it off; when unused, connect EN to the input supply for automatic startup, with an absolute maximum of 7 V.
5 IN power_in Input supply pin that must be locally bypassed; the input voltage range is 2.5 V to 5.5 V.
6 NC unconnected No connection.
