TPAM2804AAB010

TECH PUBLIC · DC-DC Converters · SOT-23-5

TPAM2804AAB010 from TECH PUBLIC, 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 EN input Chip Enable. Drive above 1.5V (V_IH) to turn on the part; drive below 0.4V (V_IL) to turn it off. Must not be left floating. Leakage ±0.01μA typ, ±1.0μA max.
2 GND power_in Ground reference for the device.
3 LX output Power switch output / switch node. Connect to the external inductor. Rated -0.3V to 6.5V; leakage ±0.01μA typ. High-side PMOS RDS(on) ≈0.29Ω, low-side NMOS RDS(on) ≈0.18Ω, peak current limit ≥1.5A.
4 VIN power_in Power supply input, 2.5V to 5.5V. Must be closely decoupled to GND with a 4.7μF or larger ceramic capacitor. Absolute max 6.5V; OVP threshold ~6.0V; UVLO ~2.1V.
5 FB input Feedback pin. A sense resistor between FB and GND programs the LED current per I_LED = V_FB / R1 with a regulated threshold of 0.1V (95-105mV).

  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tpam2804aab010-etched.step / tpam2804aab010-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpam2804aab010.step / tpam2804aab010.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tpam2804aab010.step 85 KB You want the bare part, or you mark your own boards.
tpam2804aab010-etched.step 2.5 MB You want the part with TPAM2804AAB010 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 618 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: TECH PUBLIC datasheet (6 pp, sha256 cd91466284a89dd1, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
