SK6513SD4-33 from Suntek, in a DFN1x1-4. 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 | OUT | power_out | Regulated output pin, stable with a 1µF to 10µF ceramic output capacitor (ESR 5 to 100mΩ) placed close to OUT and GND. |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable control input, active high (VENH min 1.2V, VENL max 0.4V, absolute maximum -0.3 to 44V). |
| 4 | IN | power_in | Supply input pin, 2.5 to 36V operating, decoupled with a 1µF to 10µF ceramic capacitor close to the device. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
