aoz1282ci.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

AOZ1282CI

Alpha Omega Semicon · DC-DC Converters · SOT-23-6

AOZ1282CI from Alpha Omega Semicon, 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 voltage input. High-side driver supply. Connect a 100 nF ceramic capacitor between BST and LX to develop the gate-drive rail for the internal high-side NMOS. Absolute max V(BST) to GND = V(LX) + 6V.
2	GND	power_in	Device ground return. Connect to the system ground plane with a low-impedance path close to the input capacitor.
3	FB	input	Feedback input to the error amplifier. Regulated to 0.8V (typ, 784-816 mV). Set output voltage with a resistor divider from VOUT to FB to GND. Absolute max -0.3V to 6V; input bias current typ. 500 nA.
4	EN	input	Enable pin, active high. On-threshold typ 1.2V, off-threshold max 0.4V, hysteresis ~200 mV. Connect to VIN through a current-limiting resistor; do not leave floating. Absolute max -0.3V to 40V.
5	VIN	power_in	Supply voltage input. Recommended operating range 4.5V to 36V (absolute max 40V). Device starts up when VIN rises above the UVLO threshold (typ 2.9V rising, 2.3V falling). Bypass with a low-ESR ceramic capacitor (e.g. 4.7 µF) close to the pin.
6	LX	power_out	PWM switching-node output. Drain of internal 420 mΩ high-side NMOS. Connect to the external inductor and freewheeling Schottky diode. Delivers up to 1.2A continuous; current limit typ 1.9A. Absolute max -0.7V to VIN+0.3V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`aoz1282ci.step`	97 KB	You want the bare part, or you mark your own boards.
`aoz1282ci-etched.step`	1.8 MB	You want the part with `AOZ1282CI` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 432 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.
