LN2115B025MR-G

NATLINEAR · LED Drivers · SOT-23-6L

LN2115B025MR-G from NATLINEAR, in a SOT-23-6L. 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 LX output Internal power NMOS switch drain; connect to the boost inductor and Schottky diode. Rated up to 29 V with respect to VSS; typical on-resistance 1.5 Ohm; peak switch current limit ~800 mA (VIN=3.6 V).
2 GND power_in Device ground (VSS) reference return for all internal circuitry.
3 FB input Voltage feedback input to the internal error amplifier. Regulated to a 0.25 V (0.24-0.26 V) reference; LED current is set by ILED = 0.25 V / RLED where RLED sits between the LED cathode string and GND.
4 CE input Chip enable / PWM dimming input. Logic high (VCEH >= 1 V) enables the converter at full brightness; logic low (VCEL <= 0.6 V) puts the part in standby (<= 1 uA). Applying a PWM signal (up to 100 kHz) sets the effective FB reference as VFB = Duty x 250 mV for dimming down to ~5%.
5 OVP input Overvoltage protection sense input; connect to VOUT. Trips at typically 22.5 V (20-25 V) to shut down switching and protect the LX node/output cap; absolute maximum 29 V.
6 VIN power_in Supply input. Operating range 2.5 V to 6 V (absolute max 7 V). Bypass locally with a 1 uF ceramic capacitor close to the pin.

CAD (KiCad official)

  • Symbol: LN2115B025MR-G
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6L (KiCad packages3D, STEP)
  • 3D model files: ln2115b025mr-g-etched.step / ln2115b025mr-g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ln2115b025mr-g.step / ln2115b025mr-g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ln2115b025mr-g.step 97 KB You want the bare part, or you mark your own boards.
ln2115b025mr-g-etched.step 2.4 MB You want the part with LN2115B025MR-G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 605 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.

Provenance
