# SK6152

**Suntek** · DC-DC Converters · SOT-23-6

SK6152 from Suntek, in a SOT-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 | SW | output | Power switch output, the drain of the internal MOSFET switch; connect the power inductor and output rectifier to SW. |
| 2 | GND | power_in | Ground pin for the device; the datasheet layout guidance calls for a single-point ground connection from the feedback network to GND. |
| 3 | FB | input | Feedback input with a regulated voltage of 0.6V (588 mV min, 612 mV max); connect the output resistor divider to FB. |
| 4 | EN | input | Regulator on/off control input: a high level (above 1.2V rising threshold) enables the converter and a low level (below 0.8V falling threshold) disables it; when unused, connect EN to the input supply for automatic startup. |
| 5 | IN | power_in | Input supply pin, with a recommended input voltage range of 2.3V to 5.5V. |
| 6 | NC | unconnected | Not connected. |
