# SGM6601YTN5G

**SGMICRO** · DC-DC Converters · SOT-23-5

SGM6601YTN5G from SGMICRO, in a SOT-23-5. 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 | SW | output | Switch pin connected to the drain of the internal power MOSFET; connect it to the inductor and Schottky diode, with the datasheet's maximum switch voltage rating of 40V. |
| 2 | GND | power_in | Ground pin for the device. |
| 3 | FB | input | Feedback pin that connects to the external voltage divider to program the desired output voltage, referenced to the 1.227V typical feedback reference. |
| 4 | EN | input | Enable pin; pulling it to ground forces shutdown and reduces supply current to less than 1µA, and it must not be left floating. |
| 5 | VIN | power_in | Power input supply, operating over 1.8V to 6V, that must be closely decoupled to GND with a capacitor. |
