TX6410B from XDS, in a ESOP-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 | VDD | power_in | Chip supply pin. Operating range 2.5 V to 6 V; absolute max 7 V. Recommend ~4.7 µF filter capacitor placed close to VDD and GND. Quiescent current ~60 µA typ. |
| 2 | DIM | input | PWM dimming input. Logic high enables LED output; logic low turns LED output off. VIH ≥ 0.7VDD, VIL ≤ 0.3VDD. Max dimming frequency 10 kHz (≤1 kHz recommended for best linearity). |
| 3 | NC | unconnected | No connection. Leave floating. |
| 4 | LED | output | Drain of the internal 30 V, 50 mΩ NMOS; connects to the LED cathode. Absolute maximum voltage -0.3 V to 30 V. The exposed thermal pad of the ESOP-8 is internally connected to this pin. |
| 5 | CS | input | Current-sense input. Connect through an external sense resistor Rcs to GND; the LED current is set by ILED = 100 mV / Rcs (Vcs = 96/100/104 mV min/typ/max). Absolute max voltage -0.3 V to 7 V. |
| 6 | CS | input | Current-sense input (paralleled with pin 5). Both pins tie to Rcs to GND to set output current. Use short, wide traces to minimize parasitic resistance error. |
| 7 | NC | unconnected | No connection. Leave floating. |
| 8 | GND | power_in | Chip ground reference. |

tx6410b.step |
193 KB | You want the bare part, or you mark your own boards. |

1.3 MB | You want the part with TX6410B already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 330 faces against 63 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
