Slkor SLKORMICRO Elec · DC-DC Converters · SOT-23-5
SL8088AAC from Slkor SLKORMICRO Elec, 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, tied to the drains of the internal P-ch and N-ch MOSFET switches. |
| 4 | IN | power_in | Power supply input (2.5V to 5.5V per the recommended operating range), which must be closely decoupled to GND with a 10µF or greater ceramic capacitor. |
| 5 | FB | input | Output voltage feedback pin; an internal resistive divider scales the output voltage down for comparison to the 0.6V internal reference. |
