SN3350IP05E-01 from ISSI Integrated Silicon Solution, in a SOT-89-5. 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 | Drain of the internal power switch and the switching node of the buck converter; keep the PCB trace short, with LX voltage rated -0.3 V to +50 V and switch current rated 800 mA for SOT89-5 and SOP-8. |
| 2 | GND | power_in | Ground pin that should be soldered directly to the board's ground plane to prevent ground bounce. |
| 3 | ADJ | input | Multifunction dimming/enable pin: leave floating for nominal current (VADJ = VREF = 1.2 V); below 0.2 V the output turns off, 0.3 V to 1.2 V sets 25% to 100% of nominal current, PWM duty cycle sets current, values above 1.2 V clamp at 100%, and the absolute maximum input voltage is +6 V. |
| 4 | ISENSE | input | Current-sense pin; a resistor RS connected between VIN and ISENSE sets the nominal average output current IOUTnom = 0.1/RS, with RS greater than 0.13 Ω. |
| 5 | VIN | power_in | Input supply pin rated 6 V to 40 V, which requires a 1 µF or larger X7R capacitor to ground placed close to the pin. |
