SY8105IADC

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

SY8105IADC from Silergy Corp, in a TSOT-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 FB input Feedback input referenced to 0.6V for output voltage programming via external resistor divider.
2 EN input Enable input pin with rising threshold 1.08-1.32V and falling threshold 0.9-1.1V; do not leave floating.
3 GND power_in Power ground pin.
4 IN power_in Power supply input for 4.5V-18V range with 4.35V UVLO threshold; requires ≥10µF ceramic bypass capacitor to GND.
5 LX output Switching node output pin connecting to external inductor for output LC filter with COUT.
6 BS output Bootstrap pin for high-side gate driver; connect 0.1µF ceramic capacitor between BS and LX pins.
