RY3715

RYCHIP · DC-DC Converters · SOT-23-6

RY3715 from RYCHIP, 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 SW power_out Power switch output. Drain of the internal 20V, 60mΩ NMOS power MOSFET. Connect the power inductor and Schottky output rectifier here. Absolute maximum SW voltage is 19V.
2 GND power_in Device ground return. Reference for all analog and power circuitry; tie directly to the ground plane at the input and output capacitors.
3 FB input Feedback input to the error amplifier. Regulated to VFB = 0.6V (typ, 588-612mV). Connect the top of an external resistor divider from VOUT to FB to set the output voltage: VOUT = VFB × (R1+R2)/R2.
4 EN input Regulator on/off control input. Drive high (rising threshold ≥1.2V) to enable the converter, low (falling threshold ≤0.8V) to shut it down (<1µA quiescent). Tie to IN for automatic startup when unused.
5 IN power_in Input supply pin. Operating range 2.3V to 5.5V (absolute maximum 6V). Bypass with a low-ESR ceramic capacitor (≥1µF, 22µF/25V ceramic typical) placed close to the pin.
6 NC unconnected No internal connection. Leave floating or tie to a static net; do not use as a signal via.

File Size Use it when
ry3715.step 97 KB You want the bare part, or you mark your own boards.
ry3715-etched.step 1.3 MB You want the part with RY3715 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 321 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: RYCHIP datasheet (11 pp, sha256 7bf9672b3d3fc634, retrieved 2026-08-17, tier: lcsc)
  • 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).
