SY8113ADC

Silergy Corp · DC-DC Converters · TSOT-23-6

SY8113ADC from Silergy Corp, in a TSOT-23-6. 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 passive Boot-strap pin supplying the high side gate driver; decouple to the LX pin with a 0.1uF ceramic capacitor.
2 GND power_in Ground pin.
3 FB input Output feedback pin connected to the center of the output resistor divider to program Vout=0.6*(1+R1/R2), with 0.6V reference.
4 EN input Enable control; pull high to turn on and do not float (rising threshold 1.5V, falling threshold 0.4V).
5 IN power_in Input supply pin, 4.5V to 18V operating range; decouple to GND with at least 1uF ceramic capacitor.
6 LX output Inductor pin connected to the switching node of the inductor.
