# SK6615CS5

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

SK6615CS5 from Suntek, 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 | EN | input | Enable pin for the IC: drive high to enable the part and low to disable it, with EN high input threshold of 1.2V and low input threshold of 0.5V. |
| 2 | GND | power_in | Ground reference for the regulator. |
| 3 | SW | output | Inductor connection: connect an inductor between SW and the regulator output. |
| 4 | VIN | power_in | Supply voltage input, operating from 2.6V to 5.5V. |
| 5 | FB | input | Feedback input: connect an external resistor divider from the output to FB and GND to set the output between 0.6V and Vin. |
