Suntek · DC-DC Converters · SOT-23-5
SK6619 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 | Chip enable pin: drive EN above 1.2V to turn the part on and below 0.6V to turn it off, and do not leave it floating. |
| 2 | GND | power_in | Ground pin for the regulator. |
| 3 | SW | output | Power switch output connected to the inductor and to the drains of the internal P-ch and N-ch MOSFET switches; absolute maximum SW voltage is -5V to 9V (AC, less than 10ns, while switching). |
| 4 | IN | power_in | Power supply input over a 2.7V to 6V range, which must be closely decoupled to GND with a 10µF or greater ceramic capacitor. |
| 5 | FB | input | Output voltage feedback pin connected to an internal resistive divider that is compared to the 0.6V internal reference (feedback voltage 0.585V to 0.615V). |
