SL8205FC

Slkor SLKORMICRO Elec · DC-DC Converters · SOP-8-EP

SL8205FC from Slkor SLKORMICRO Elec, in a SOP-8-EP. 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 BS power_out Bootstrap pin that supplies the high-side gate driver and should be decoupled to LX with a 0.1µF ceramic capacitor; BS-LX is rated -0.3 to 6.0 V.
2 LX passive Inductor pin connected to the switching node of the inductor; LX is rated -0.3 to +25 V.
3 EN input Enable control with an accurate 1.2V falling threshold (1.1 V to 1.3 V) that allows a programmable turn-on delay through an external RC; rated -0.3 to +25 V.
4 SS passive Soft-start programming pin; connect a capacitor to ground, with Tss = Css × 0.6 V / 10µA.
5 FB input Output feedback pin connected to the centre point of the output resistor divider, with Vout = 0.6 × (1 + R1/R2) and VFB of 0.591 V to 0.609 V.
6 VCC power_out Internal 5V LDO output for internal analog and driver circuits, bypassed to GND with 1µF, usable for an external DC load of 20mA or less, and tracking VIN when VIN is below 5 V; rated -0.3 to 6.0 V.
7 VIN power_in Input supply for all internal control circuitry with a 4.5 V to 20 V supply range, requiring a decoupling capacitor to ground placed close to the pin.
8 VIN power_in Input supply for all internal control circuitry with a 4.5 V to 20 V supply range, requiring a decoupling capacitor to ground placed close to the pin.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
