LGS63032B6 from Legend Si LGS63032, in a SOT-23-6. 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	SW	power_out	Internal power switch node. Connects externally to the boost inductor and Schottky rectifier (e.g. SS26). Rated for 2A peak switch current and up to 60V.
2	GND	power_in	Device ground reference pin. Return path for all internal circuitry and the low side of the input decoupling capacitor.
3	FB	input	Feedback input pin. Connects to the top of the external RSENSE current-sense resistor. Regulated at VFB = 0.2V (typ); output current is set by IOUT = VFB / RSENSE = 0.2 / RSENSE (A). FB bias current ≈ 50nA.
4	EN	input	Enable and dimming input. Accepts a DC level for analog dimming (0.6V-1.22V active range on LGS63030) or a PWM waveform for digital dimming (100Hz-100kHz on LGS63032). Must not be left floating; drive low to disable (EN falling threshold ~0.35V on '2' variant). For pure enable without dimming, apply between 1.2V and 6V via a divider.
5	OVP	input	Output over-voltage protection sense pin. Connects to a resistor divider between the boost output and GND. Triggers protection when the pin rises above 1V (typ), releases at 0.86V. Abs-max: -0.3V to +6V.
6	VIN	power_in	Supply input pin, 3.0V-60V. Bypass with a 4.7µF or larger X7R/X5R ceramic capacitor placed as close as possible to VIN and GND. UVLO rising ~3.0V, falling ~2.6V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lgs63032b6.step`	97 KB	You want the bare part, or you mark your own boards.
`lgs63032b6-etched.step`	2.6 MB	You want the part with `LGS63032B6` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 596 faces against 117 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.
