JW5361FMSOTB#TR from JoulWatt Tech, 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 | GND | power_in | Ground pin for the regulator. |
| 2 | SW | output | SW is the switching node that supplies power to the output, and the output LC filter is connected from SW to the output load. |
| 3 | VIN | power_in | Input voltage pin that supplies the IC; connect a 4.5V to 18V supply and bypass VIN to GND with a suitably large capacitor. |
| 4 | FB | input | Output feedback pin that senses the output voltage and is regulated by the control loop to 0.765V, with a resistive divider connected at FB. |
| 5 | EN | input | Drive EN high to turn on the regulator and low to turn off the regulator; the regulator shuts down when EN is driven below 0.4V. |
| 6 | BST | passive | Connect a 0.1μF capacitor between BST and SW to supply voltage for the top switch driver. |
