TPS61040DRVR from Texas Instruments, in a WSON-6-EP(2x2). 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 reference for device |
| 2 | VIN | power_in | Power supply input pin, operating range 1.8V to 6V |
| 3 | EN | input | Enable input pin; pull to ground for shutdown mode with shutdown current ≤1μA; pin must be terminated and must not be left floating |
| 4 | FB | input | Feedback input pin for output voltage programming via external voltage divider network |
| 5 | NC | unconnected | No connection |
| 6 | SW | output | Switch output node connected to drain of internal power MOSFET; connect external inductor and Schottky diode |
| 7 | Thermal PAD | passive | Exposed thermal pad; solder to ground plane for thermal and mechanical performance |
