Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | input | Switch pin connected to the drain of the internal power MOSFET. Connect the inductor and the Schottky diode to this pin. Maximum switch voltage 30V; internal MOSFET current limit 400mA (TPS61040), RDS(on) typ 600mΩ. |
| 2 | GND | power_in | Device ground reference. All voltages are referenced to this pin. |
| 3 | FB | input | Feedback pin. Connect to the external resistor divider from VOUT to program the desired output voltage. Internal reference (VFB) is 1.233V typical (1.208V-1.258V). |
| 4 | EN | input | Enable pin. Pulling to ground forces the device into shutdown mode (supply current <1µA). Must not be left floating and needs to be terminated. VIH ≥ 1.3V, VIL ≤ 0.4V. |
| 5 | VIN | power_in | Supply voltage pin. Input voltage range 1.8V to 6V (absolute max 7V). Bypass with 4.7µF input capacitor. |
CAD and provenance
The plain and marked STEP/GLB files are original Adom nominal reconstructions from TI's package drawing: 2.9 × 1.6 mm body, 2.9 mm lead span, 0.95 mm pitch and 1.20 mm height. The prior generic model was 1.55 mm tall, above TI's 1.45 mm maximum. Lead bends, mold taper and colors are illustrative; this is not manufacturer CAD or a tolerance envelope.
The marked variant adds a subtle virtual full-MPN identification layer, 0.005 mm above the package. It is neither a factory mark nor a recessed manufacturing feature. Board-use assets exclude the hero's nonphysical footprint and signal overlays.
The existing KiCad-derived symbol and footprint retain their original library terms. The footprint is a generic project-compatible variant; compare its land pattern with the manufacturer example before selecting a process. See correction and provenance, current manufacturer datasheet, and TI source.
Only exact ordering code TPS61040DBVR is asserted here. Earlier concatenated variant strings were unsupported and have been removed.
Local model inspection and native symbol/footprint validation are separate from physical qualification and published wiki visual review.
