GBI1400TKBR from GOSEMICON, in a TSOT-23-6L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BOOT | input | Power supply for the high-side power MOSFET gate driver; a 0.1uF or greater ceramic capacitor must be connected between the BOOT pin and the SW node. |
| 2 | GND | power_in | Power ground; the GND pin should be connected directly to the thermal pad beside the IC with an 8mil max thermal via recommended. |
| 3 | FB | input | Buck converter output feedback sensing input; a resistor divider from VOUT to FB sets the output, and the device regulates FB to the internal 0.8V reference typically (FB absolute maximum is 6V). |
| 4 | EN | input | Enable logic input that supports high voltage up to VIN, with precision thresholds of 1.25V rising and 1.1V falling for programmable UVLO; this pin cannot be floating. |
| 5 | VIN | power_in | Power supply input with an operating range of 4.6V to 40V that must be locally bypassed. |
| 6 | SW | output | Switching node of the buck converter; SW to GND is rated -1V to 45V absolute maximum (SW to GND, less than 30ns transients: -2V to 45V). |
