LV2842XLVDDCR

Texas Instruments · DC-DC Converters · SOT-23-6

LV2842XLVDDCR from Texas Instruments, 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 CB passive Bootstrap capacitor node providing gate bias voltage for the internal high-side switch FET. Connect a bootstrap capacitor (Cboot) between CB and SW; operating range 3.8 V to 45 V, absolute maximum 50 V.
2 GND power_in Device ground connection. Common return for input supply and internal circuitry.
3 FB input Feedback pin for the internal error amplifier. Set the output voltage using a resistor divider: VOUT = VFB * (1 + R1/R2), with VFB = 0.765 V nominal (0.746-0.784 V). Absolute maximum 7 V.
4 /SHDN input Active-low enable/shutdown input (high-voltage tolerant, 0-40 V range). Internal pull-up current source; pull below 1.25 V to disable, float or drive high to enable. Can be tied to a resistor divider to adjust the input UVLO threshold. Enable threshold 1.05-1.38 V.
5 VIN power_in Unregulated power input for the internal supply and the drain of the internal high-side MOSFET. Operating range 4 V to 40 V, absolute maximum 45 V.
6 SW output Switch node output from the internal high-side MOSFET (RDS(on) ~500 mΩ). Connect the external inductor, catch diode, and bootstrap capacitor here. Range -1 V to 40 V (absolute maximum -2 V for 30 ns, 45 V positive).

CAD (KiCad official)

  • Symbol: LV2842XLVDDCR
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: lv2842xlvddcr-etched.step / lv2842xlvddcr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lv2842xlvddcr.step / lv2842xlvddcr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
lv2842xlvddcr.step 97 KB You want the bare part, or you mark your own boards.
lv2842xlvddcr-etched.step 2.1 MB You want the part with LV2842XLVDDCR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 521 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

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (15 pp, sha256 315cb41a69ad8b7c, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
