# LM3410XQMF

**Texas Instruments** · LED Drivers · SOT-23-5

LM3410XQMF from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Output switch; connect to the inductor and output diode; maximum 26.5 V absolute rating. |
| 2 | GND | power_in | Signal and power ground pin; place the bottom resistor of the feedback network as close as possible to this pin. |
| 3 | FB | input | Feedback pin; connect to external resistor to set output current; maximum 3 V absolute rating. |
| 4 | DIM | input | Dimming and shutdown control input; logic high enables operation with 0% to 100% duty cycle; do not allow to float or exceed VIN + 0.3 V; maximum 7 V absolute rating. |
| 5 | VIN | power_in | Supply voltage pin for power stage and input supply voltage; recommended 2.7 to 5.5 V; maximum 7 V absolute rating. |
