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).
