TPS62120DCNR from Texas Instruments, in a SOT-23-8. 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 | VIN | power_in | Power supply input pin supporting 2 V to 15 V input range. |
| 2 | GND | power_in | Ground return supply pin. |
| 3 | EN | input | Enable control pin; high level activates device, low level initiates shutdown; pin must be terminated. |
| 4 | SGND | power_in | Open-drain discharge output with typical 370 Ω RDS(ON); conducts SGND to GND during shutdown or UVLO condition. |
| 5 | FB | input | Feedback input pin; connect external resistor-divider network to set output voltage regulation point. |
| 6 | PG | output | Open-drain power good output indicator; maximum sink current 500 µA. |
| 7 | SW | output | Switching node connected to internal MOSFET switches; connection point for output inductor; do not connect to VIN, VOUT, or GND. |
| 8 | VOUT | input | Output voltage sense pin; must be connected to output filter capacitor. |
