TPS54302DDCT from Texas Instruments, in a TSOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground pin. Source terminal of the low-side power NFET as well as the ground terminal for the controller circuit. Connect sensitive VFB return to this GND at a single point. |
| 2 | SW | output | Switch node connection between the high-side NFET (drain to VIN) and low-side NFET (source to GND). Connects to the external inductor. Absolute max -0.3 V to 30 V (5 V for 20 ns transient minimum). |
| 3 | VIN | power_in | Input voltage supply pin. Drain terminal of the high-side power NFET. Recommended operating range 4.5 V to 28 V; absolute maximum 30 V. Requires local bypass capacitor to GND. |
| 4 | FB | input | Converter feedback input to the error amplifier. Connect to the output voltage via a resistor divider to set VOUT. Internal reference VFB = 0.596 V typ. |
| 5 | EN | input | Enable pin. Float (internal pull-up) to enable the converter. Rising enable threshold ≈ 1.21 V typ, falling ≈ 1.19 V typ. Absolute max 7 V. |
| 6 | BOOT | power_out | Bootstrap supply for the high-side NFET gate drive circuit. Connect a 0.1-µF ceramic capacitor between BOOT and SW pins. Absolute max BOOT-SW = 7 V. |
