TPS563249DDCR 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 low-side power NFET as well as the ground terminal for controller circuit. Connect sensitive VFB to this GND at a single point. |
| 2 | SW | output | Switch node connection between high-side NFET and low-side NFET. Connects to the external inductor. Absolute max -2V to 19V (steady state). |
| 3 | VIN | power_in | Input voltage supply pin. The drain terminal of high-side power NFET. Recommended operating range 4.5V to 17V; absolute max 19V. |
| 4 | VFB | input | Converter feedback input. Connect to output voltage with feedback resistor divider. Regulates to internal reference of 600mV (typ). |
| 5 | EN | input | Enable input control. Active high and must be pulled up to enable the device. Rising threshold 1.27V typ; internal ~1MΩ pulldown to GND. |
| 6 | VBST | power_out | Supply input for the high-side NFET gate drive circuit (bootstrap). Connect a 0.1 µF capacitor between VBST and SW pins. |
