TPS563231DRLR from Texas Instruments, 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 supply pin, drain of high-side NFET; operating range 4.5 V to 17 V. |
| 2 | SW | output | Switch node connection between high-side NFET and low-side NFET. |
| 3 | GND | power_in | Power ground terminal connected to source of low-side FET internally. |
| 4 | BST | power_out | Bootstrap supply for high-side NFET gate driver; connect 0.1 µF capacitor between BST and SW pins. |
| 5 | EN | input | Enable input control with hysteresis; high level 1.10 to 1.42 V enables operation, low level 1.00 to 1.30 V disables; do not leave floating. |
| 6 | FB | input | Converter feedback input for voltage regulation with internal reference voltage 600 mV. |
