# SL2359

**Slkor SLKORMICRO Elec** · DC-DC Converters · SOT-23-6

SL2359 from Slkor SLKORMICRO Elec, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BS | passive | Bootstrap pin. A capacitor (typically 0.1µF) is connected between LX and BS to form a floating supply that drives the high-side switch gate above VIN. |
| 2 | GND | power_in | Ground pin. Return path for internal control circuitry and low-side switch current. Connect directly to the system ground plane with a low-impedance path. |
| 3 | FB | input | Output voltage feedback input. Connect to the center tap of an external resistor divider from VOUT to set the output voltage. Internal reference VREF = 0.8V (±2%); typical FB leakage current is ±0.5µA. |
| 4 | EN | input | Enable input. Drive to logic-high (VEN > ~1.1V typical rising threshold) to enable the IC; drive to logic-low to disable and enter micro-power shutdown mode (~5µA). Do not leave EN floating. Absolute max: VIN. |
| 5 | IN | power_in | Power supply input. Connect the input supply (4.5V to 30V; absolute max 33V) with a local input decoupling capacitor (typically 10µF ceramic). |
| 6 | LX | power_out | Switching node. Internal high-side and low-side MOSFET connection. Connect to the external inductor which feeds the output. Absolute max -0.3V to 33V (35V for <10ns transient). |

## CAD (KiCad official)

- Symbol: `SL2359`
- Footprint: `Package_TO_SOT_SMD:SOT-23-6`
- 3D model: SOT-23-6 (KiCad packages3D, STEP)
- 3D model files: `sl2359-etched.step` / `sl2359-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sl2359.step` / `sl2359.glb` are the bare package body.
