TMI3244T

TMI · DC-DC Converters · SOT-23-6

TMI3244T from TMI, 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 GND power_in Ground pin. Device return; connect to a large copper ground plane for thermal performance and low-impedance return of the switching current loop.
2 LX output Switching node. Connects the internal high-side and low-side power MOSFETs to the external inductor. Absolute max -0.3V to 20V (−5V to 22V for <10ns transients).
3 VIN power_in Power supply input pin. Recommended operating range 4.5V to 18V (absolute max 20V). Bypass locally with ceramic capacitors close to the pin.
4 FB input Output voltage feedback input. Connect to the center point of the external R1/R2 resistor divider from VOUT to GND. Internal reference VREF is typically 0.765V; absolute max -0.3V to 6V.
5 EN input Enable input. Drive logic-high (typ threshold 0.9V, hysteresis 100mV) to enable the IC; drive logic-low to enter micro-power shutdown. Do not leave floating. Absolute max 20V.
6 BS passive Bootstrap pin. Connect a 100nF ceramic capacitor between LX and BS to form a floating supply for the high-side MOSFET gate driver. Absolute max -0.3V to 23V.

CAD (KiCad official)

  • Symbol: TMI3244T
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: tmi3244t-etched.step / tmi3244t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmi3244t.step / tmi3244t.glb are the bare package body.

Provenance

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

  • Datasheet: TMI datasheet (None pp, sha256 6160d99e2fa14990, 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).
