RY3708

RYCHIP · DC-DC Converters · SOT-23-6

RY3708 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 80mΩ NMOS power switch (4A typical current limit, absolute max 10V). Connect the boost inductor and Schottky output rectifier here.
2 GND power_in Device ground return. Provides the return path for the internal power MOSFET and analog circuitry; tie feedback-divider ground here through a single-point star.
3 FB input Feedback input to the error amplifier, regulated to VFB = 0.6V (588-612mV). Set VOUT with a resistor divider: VOUT = 0.6V × (R1+R2)/R2. Input bias current is roughly -10nA (-50nA max) at VFB=0.6V.
4 EN input Regulator on/off control input. Logic-high (threshold ~1V, absolute max 6V) enables the converter; logic-low shuts it down (IIN ≤ 1µA). Tie to VIN for automatic start-up; do not leave floating.
5 IN power_in Input supply pin, 2.5V to 5.5V (absolute max 6V). Bypass locally with a low-ESR ceramic capacitor (22µF typical) placed as close as possible to the pin.
6 NC unconnected No internal connection. Leave floating or tie to ground for mechanical stability; do not use for signal routing.

  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: ry3708-etched.step / ry3708-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ry3708.step / ry3708.glb are the bare package body.

Provenance

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

  • Datasheet: RYCHIP datasheet (9 pp, sha256 259165a62f88b37e, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
