LM2833XSD from Texas Instruments, in a WSON-10-EP(3x3). 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 | VINC | power_in | Input supply for internal bias and control circuitry; bypass to GND. |
| 2 | EN | input | Enable control input; logic high enables operation; do not allow to float or exceed VIN + 0.3V. |
| 3 | SGND | power_in | Signal (analog) ground; place bottom resistor of feedback network as close as possible to this pin for good load regulation. |
| 4 | NC | unconnected | No user function; connect this pin to GND. |
| 5 | FB | input | Feedback pin; connect to external resistor divider to set output voltage. |
| 6 | PGND | power_in | Power ground pin; provides ground return path for the internal driver. |
| 7 | SW | output | Switch pin; connect to inductor and catch diode. |
| 8 | SW | output | Switch pin; connect to inductor and catch diode. |
| 9 | VIND | power_in | Input supply voltage; connect a bypass capacitor locally from this pin to PGND. |
| 10 | VIND | power_in | Input supply voltage; connect a bypass capacitor locally from this pin to PGND. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
