BL9362

BL Shanghai Belling · DC-DC Converters · SOT-23-6L

BL9362 from BL Shanghai Belling, 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 BST passive Bootstrap pin for the high-side switch. Connect a 0.1μF (or larger) capacitor between BST and LX to supply gate drive for the top NMOS. Absolute max: −0.3V to LX+6V.
2 GND power_in Analog ground reference for the IC. Tie to the system ground plane and to the return of the input/output capacitors.
3 FB input Output feedback input. Senses the output voltage via an external resistive divider; regulated by the control loop to 795mV (typ). Absolute max: −0.3V to 6V.
4 EN input Enable input. Drive high (≥1.23V typ) to turn on the regulator, low (≤1.13V typ) to shut it down. May be tied directly to VIN. Absolute max: −0.3V to VIN+0.3V. IEN ≈ 4.4μA at 16V.
5 VIN power_in Input supply pin. Accepts 4.5V to 60V. Bypass to GND with a suitably large capacitor (typ. 10μF + 0.1μF) to eliminate input noise.
6 LX power_out Switching node output. Drain of the internal 850mΩ high-side NMOS. Connect the external inductor and catch diode here to feed the output LC filter. Absolute max: −0.3V to VIN+0.3V.

Two STEP files. Same geometry, different body top:

File Size Use it when
bl9362.step 97 KB You want the bare part, or you mark your own boards.
bl9362-etched.step 1.6 MB You want the part with BL9362 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 384 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: BL Shanghai Belling datasheet (7 pp, sha256 a7737ee5bd7c3cbe, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
