SGMICRO · DC-DC Converters · TSOT-23-6
SGM61230XTN6G from SGMICRO, 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 | GND | power_in | Device ground reference pin for the converter. |
| 2 | SW | output | Switching node connecting the internal lower and upper power MOSFETs; connect it to the output inductor and the bootstrap capacitor, with SW rated -0.3V to 30V (-5V to 30V for 20ns transients). |
| 3 | VIN | power_in | Input supply pin that powers the control circuitry and power converter over 4.5V to 28V, protected by UVLO, and should be decoupled close to VIN and GND with high-frequency ceramic capacitors. |
| 4 | FB | input | Feedback sense pin for output voltage programming, normally regulated at 0.603V, with a recommended voltage range of -0.1V to 3V. |
| 5 | EN | input | Device enable pin that runs the device when high and shuts it down when low, with the pin left floating enabling the device; recommended voltage range is -0.1V to 5.5V. |
| 6 | BOOT | output | Bootstrap pin that requires a 0.1µF CBOOT between BOOT and SW placed close to the device with no series resistor, with a recommended BOOT-SW voltage of -0.1V to 5.5V. |
