SGM61412AXTN6G from SGMICRO, in a SOT-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 | GND | power_in | Ground pin that is the reference for the input and regulated output voltages and requires special layout considerations. |
| 2 | SW | output | Switching node output that connects to the output inductor and bootstrap capacitor and should be kept small on the PCB to minimize capacitive coupling, noise coupling and radiation. |
| 3 | VIN | power_in | Power supply input for 4.5V to 42V operation that powers the control circuitry, is monitored by UVLO, and must be decoupled to GND by input capacitors placed as close as possible to the GND pin. |
| 4 | FB | input | Feedback input that the SGM61412 regulates to 0.83V, connected to the midpoint of the output feedback resistor divider. |
| 5 | EN | input | Active-high enable input with an internal pull-up current source that disables the device when pulled below 0.9V and enables it when floated, with input UVLO adjustable by a resistor divider. |
| 6 | BOOT | power_out | Bootstrap pin that provides a drive voltage above VIN to the high-side power switch, with a 0.1µF CBOOT required as close as possible between this pin and SW. |
