JW5393FSOTI#TR from JoulWatt Tech, in a SOT-563. 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 | VIN | power_in | Input voltage pin that supplies the IC; connect a 4.5V to 18V supply and bypass it to GND with a suitably large capacitor (VIN absolute maximum is -0.3V to 20V). |
| 2 | SW | power_out | Switching node that supplies power to the output; the output LC filter connects from SW to the output load (SW absolute maximum is -0.3V (-5V for 10ns) to 20V (22V for 10ns)). |
| 3 | GND | power_in | Ground pin. |
| 4 | BST | passive | Connect a 0.1μF capacitor between BST and SW to supply current for the top switch driver (BST absolute maximum is SW-0.3V to SW+4V). |
| 5 | EN | input | Drive high to turn the regulator on and low to turn it off; the regulator shuts down when EN is below 0.4V (EN absolute maximum is -0.3V to 20V). |
| 6 | FB | input | Output feedback pin that senses the output voltage and is regulated by the control loop to 0.8 V; connect a resistive divider at FB (absolute maximum on all other pins is 4V). |
