SY7152ABC

Silergy Corp · DC-DC Converters · SOT-23-6

SY7152ABC from Silergy Corp, 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 Inductor switching node. Connect an inductor between IN pin and LX pin. Internal low-side main FET (Rds(on) = 150mΩ) switches this node at 1MHz. Absolute max 18V.
2 GND power_in Ground pin. Return for input capacitor and internal low-side FET. Maximize copper area to this pin for best thermal and noise performance.
3 FB input Feedback pin. Connect resistor R1 between VOUT and FB, and R2 between FB and GND to program output voltage: VOUT = 0.6V × (R1/R2 + 1). Reference voltage 0.6V (±2%).
4 EN input Enable control. Drive high (>1.5V) to turn on the part; low (<0.4V) to shut down. Do not leave floating. Input current ~100nA max. Absolute max 18V.
5 IN power_in Input supply pin. 3V to 8V recommended operating range (absolute max 18V). Decouple to GND with a 1uF (typ. 10uF X5R) ceramic capacitor placed close to the pin.
6 NC unconnected No connection. Leave floating or tie to GND per board convention.

Two STEP files. Same geometry, different body top:

File Size Use it when
sy7152abc.step 97 KB You want the bare part, or you mark your own boards.
sy7152abc-etched.step 1.7 MB You want the part with SY7152ABC already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 422 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: Silergy Corp datasheet (9 pp, sha256 9f35e0b521158848, retrieved 2026-08-17, tier: manufacturer)
  • 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).
