TPS54308DDCT 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 for low-side NFET source and control circuit; provides reference for output voltage feedback. |
| 2 | SW | output | Switch node connection between high-side and low-side NFET; rated -5V to 30V at 20ns transient voltage. |
| 3 | VIN | power_in | Input power supply pin rated 4.5V to 28V; drain terminal of high-side power NFET. |
| 4 | FB | input | Converter feedback input connected via external resistor divider to output voltage; internal reference voltage 0.596V nominal. |
| 5 | EN | input | Enable control pin with internal pull-up current; device enables when EN > 1.28V rising threshold, disables when EN < 1.19V falling threshold. |
| 6 | BOOT | output | Bootstrap supply for high-side NFET gate driver circuit; connect 0.1µF ceramic capacitor between BOOT and SW pins for proper operation. |
