TPS54202HDDCT from Texas Instruments, 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 serving as source terminal of low-side power NFET and controller circuit ground reference; connect sensitive VFB single point to this pin. |
| 2 | SW | output | Switch node connecting high-side and low-side NFET that outputs between 0V and VIN at switching frequency. |
| 3 | VIN | power_in | Input voltage supply pin rated 4.5V to 28V serving as drain terminal of integrated high-side power NFET. |
| 4 | FB | input | Converter feedback input for output voltage regulation connected through external resistor divider network. |
| 5 | EN | input | Enable pin with internal pull-down resistor (~1MΩ); leave floating or pull below 1.16V threshold to disable device. |
| 6 | BOOT | power_out | Bootstrap power supply output for high-side NFET gate drive circuit with 0.1μF ceramic capacitor required between BOOT and SW. |
