RY3750

RYCHIP · DC-DC Converters · SOT-23-5

RY3750 from RYCHIP, 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 LX output Power switch output. Drain of the internal N-channel MOSFET switch; connect the boost inductor and Schottky rectifier here. Node swings between GND and up to 30V at 1.2MHz.
2 GND power_in Device ground return. Tie to a solid ground plane for heat sinking and noise protection.
3 FB input Feedback input for the output voltage regulation loop. Internal reference is 1.23V (typical); set VOUT with an external resistor divider from VOUT to FB to GND. FB bias current is -50 to -10 nA.
4 EN input Regulator on/off enable input. Logic high (>~1V) turns the converter on; logic low turns it off (shutdown IIN ~0.1 uA). Tie to VIN for automatic startup when not used. Absolute max 6V.
5 IN power_in Input supply pin, 2.5V to 5.5V operating (abs max 6V). Must be locally bypassed with a low-ESR ceramic capacitor (22uF recommended, X5R/X7R).

  • Symbol: RY3750
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ry3750-etched.step / ry3750-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ry3750.step / ry3750.glb are the bare package body.

Provenance

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

  • Datasheet: RYCHIP datasheet (7 pp, sha256 3c00582ad13b7c1a, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
