ZTP7108T

ZILLTEK · DC-DC Converters · TSOT-23-5L

ZTP7108T from ZILLTEK, in a TSOT-23-5L. 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 EN input Enable control input. Drive above VENH (min 1.5V) to enable the converter; drive below VENL (max 0.4V) to shut down (IS < 1uA). Do not exceed Vin.
2 GND power_in Ground reference for the IC and power return for the internal synchronous rectifier.
3 SW output Power switch node output. Connects to the external inductor; carries up to 3A peak switch current at 1.5MHz. Absolute range -0.3V to Vin+0.3V.
4 Vin power_in Main supply input, 2.5V to 5.5V. Bypass with a 4.7uF (X5R/X7R) ceramic capacitor close to the pin. Absolute maximum 6V.
5 FB input Feedback input to the internal error amplifier. Regulates to VREF = 0.6V; set Vout with an external divider using Vout = 0.6 x (1 + R1/R2). A small feed-forward cap (10-47pF, 33pF typical) in parallel with R1 improves transient response.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ztp7108t.step 85 KB You want the bare part, or you mark your own boards.
ztp7108t-etched.step 1.4 MB You want the part with ZTP7108T already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 352 faces against 102 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: ZILLTEK datasheet (8 pp, sha256 722b057851842035, 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).
