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 | Switch pin. Connect this pin to the output inductor and Schottky diode. |+| 2 | BOOT | output | MOSFET drive bootstrap pin. Connect a 10-nF ceramic capacitor from this pin to SW. |+| 3 | DIM | input | Input for PWM dimming. Connect a logic-level PWM signal to this pin to enable and disable the power MOSFET and reduce the average light output of the LED array. |+| 4 | GND | power_in | Ground pin. Connect this pin to system ground. |+| 5 | CS | input | Current sense feedback pin. Set the current through the LED array by connecting a resistor from this pin to ground. |+| 6 | RON | input | ON-time control pin. A resistor connected from this pin to VIN sets the regulator controlled ON-time. |+| 7 | VCC | power_out | Output of the internal 7-V linear regulator. Bypass this pin to ground with a minimum 0.1-µF ceramic capacitor with X5R or X7R dielectric. |+| 8 | VIN | power_in | Input voltage pin. Nominal operating input range for this pin is 6 V to 42 V (LM3402) or 6 V to 75 V (LM3402HV). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VSSOP-8-0.65mm |+| Category | LED Drivers |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `LM3402MM`+- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`+- 3D model: VSSOP-8-0.65mm (KiCad packages3D, STEP)+- 3D model files: `lm3402mm-etched.step` / `lm3402mm-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm3402mm.step` / `lm3402mm.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/lm3402) (43 pp, sha256 `8c6e2cc4aaa8c98a`, retrieved 2026-10-01, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-4-5-20251001` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
