QX2303L30F

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

QX2303L30F 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. VIH >= 0.4*VOUT, VIL <= 0.2V. Input current +/-0.1uA typical. Pulling low puts the chip in shutdown (IINQ <= 1uA).
2 VOUT power_in Output voltage sense / bootstrap supply pin. Connects to the boosted output rail (nominal 3.0V for QX2303L30F). Datasheet labels this pin type as 'input' since the internal error amplifier and bias derive power from here. Absolute max 7V.
3 NC unconnected No connection. Leave floating.
4 GND power_in Power ground / reference return for the converter.
5 LX output Internal MOSFET switch drain / inductor node. Connects to the boost inductor and Schottky diode anode. ILX max 1000mA; current limit 600-1000mA (typ 800mA). Absolute max 7V.

Provenance

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

  • Datasheet: QX Micro Devices datasheet (14 pp, sha256 d242bea889c7a76b, 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.
