SD2350D50A from SHOUDING, in a SOT-23. 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 | Vss | power_in | Ground pin, which must be well grounded because the internal zero potential otherwise shifts with switching current and makes operation unstable. |
| 2 | Lx | output | Switching pin (or Ext drive for an external transistor) whose LX switch driver produces a turn-off voltage spike, with the datasheet giving a switch on-current of 450 mA at VLX=0.4V for the 3.3V version. |
| 3 | OUT | power_out | Boost output pin, which needs an output capacitor of at least 47 µF with low ESR (tantalum or high-frequency type) placed as close as possible, and the device is rated for 800 mA output current (Iout) maximum. |
