jw5026.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 6 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

JW5026

JoulWatt Tech · DC-DC Converters · SOT-23-6

JW5026 from JoulWatt Tech, 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 BST passive Bootstrap pin for the top switch driver. Connect a 0.1uF (or larger) capacitor between BST and SW to supply gate-drive current to the internal high-side N-channel MOSFET. Absolute maximum voltage is SW-0.3V to SW+5V.
2 GND power_in Device ground. Return path for internal circuitry and the low-side power MOSFET.
3 FB input Output voltage feedback pin. FB is regulated by the internal control loop to 800mV (typ). Connect a resistive divider from Vout to FB to GND to set the output voltage.
4 EN input Enable input. Drive EN high to turn on the regulator; drive low to shut down. Shutdown threshold is 1.3V typical (1.18V min / 1.42V max) with 120mV typical hysteresis. Absolute maximum voltage is -0.3V to 44V.
5 VIN power_in Input supply pin. Accepts 4.7V to 40V. Bypass VIN to GND with a suitably large ceramic capacitor (e.g. 4.7uF) close to the pin to filter input noise. Absolute maximum voltage is -0.3V to 44V.
6 SW power_out Switching node connecting the drain of the internal high-side and low-side MOSFETs. Connect the external inductor of the output LC filter from SW to the load. Absolute maximum voltage is -0.3V (-7V for 5ns) to 44V (45V for 5ns).

  • Symbol: JW5026
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: jw5026-etched.step / jw5026-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); jw5026.step / jw5026.glb are the bare package body.

jw5026.step 97 KB You want the bare part, or you mark your own boards.
jw5026-etched.step 1.5 MB You want the part with JW5026 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 359 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.
