# SGM61410XN6G

**Tokmas** · DC-DC Converters · TSOT-23-6

SGM61410XN6G from Tokmas, in a TSOT-23-6. 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 | BST | power_out | Power supply for the high-side power MOSFET gate driver; a 0.1uF or greater ceramic capacitor must be connected between BST and SW. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | FB | input | Buck converter output feedback sensing input; a resistor divider from VOUT sets the output voltage, and the device regulates FB to the internal 0.81V reference typically. |
| 4 | EN | input | Enable logic input that accepts voltages up to VIN, with precision thresholds of 1.21V rising and 1.1V falling for programmable UVLO. |
| 5 | VIN | power_in | Power supply input for the 4.5V to 40V operating range, which must be locally bypassed. |
| 6 | SW | power_out | Switching node of the buck converter, with an absolute maximum rating of -1V to 42V. |
