QX2304L30F

QX Micro Devices · DC-DC Converters · SOT-23-5

QX2304L30F from QX Micro Devices, in a SOT-23-5. 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 EN input Chip enable input, active high. Drive above 0.4*VOUT to enable the converter; drive below 0.2 V to place the device into standby (INQ <= 1 uA).
2 VOUT power_out Regulated boost output and internal feedback sense pin. Connect the output capacitor (COUT = 100 uF typical) here. Output is factory-trimmed (2.5V-3.6V range, 0.1V steps; 3.0V for the 30 suffix) with +/-2.5% accuracy. Absolute max 7 V.
3 NC unconnected No connect. Leave floating.
4 GND power_in Device ground reference. Connect to the system ground plane.
5 LX output Internal synchronous power switch drain / inductor switching node. Connect the boost inductor (L1 = 47 uH typical) between VIN and LX. Peak current limit 600/800/1000 mA (min/typ/max); absolute max 1000 mA continuous; absolute max voltage 7 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
qx2304l30f.step 85 KB You want the bare part, or you mark your own boards.
qx2304l30f-etched.step 2.1 MB You want the part with QX2304L30F already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 502 faces against 102 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: QX Micro Devices datasheet (14 pp, sha256 d147751aef814a16, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
