RT9293BGJ6

Richtek Tech · LED Drivers · SOT-23-6

RT9293BGJ6 from Richtek Tech, 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 LX power_out Switching pin. Drain of the internal N-MOSFET switch; connects to the boost inductor and Schottky diode anode. Rated -0.3V to 50V absolute maximum.
2 GND power_in Ground pin. Return for both the power switch and control circuitry.
3 FB input Feedback pin. Connect the LED string return through a sense resistor R_SET to GND; the loop regulates FB to V_REF (300mV typ for RT9293B) to set the LED current.
4 EN input Chip enable (active high). Logic-high (V_IH >= 1.4V) turns the converter on; logic-low (V_IL <= 0.5V) shuts it down. Rated -0.3V to 6V.
5 VOUT power_out Output voltage sense pin. Connects to the boost output rail for OVP monitoring. Rated -0.3V to 46V; OVP threshold 46V (RT9293A/B default 50V) or 17.5V (RT9293B-20 option).
6 VIN power_in Input supply pin. Operating range 2.5V to 5.5V (abs max 6V). Bypass with a 2.2uF ceramic capacitor to GND.

CAD (KiCad official)

  • Symbol: RT9293BGJ6
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: rt9293bgj6-etched.step / rt9293bgj6-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rt9293bgj6.step / rt9293bgj6.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
rt9293bgj6.step 97 KB You want the bare part, or you mark your own boards.
rt9293bgj6-etched.step 2.4 MB You want the part with RT9293BGJ6 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 555 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: Richtek Tech datasheet (13 pp, sha256 f3056eb2a850b07e, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
