SY8511BADC

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

SY8511BADC 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 Bootstrap pin that supplies the high-side gate driver; connect a 0.1µF ceramic capacitor in series with a 10Ω resistor between BS and LX.
2 GND power_in Ground pin.
3 FB input Output feedback pin, connected to the center point of the output resistor divider to set VOUT = 0.6×(1+R1/R2), with a 0.6V ±1% reference.
4 EN input Enable control: pull high to turn on (rising threshold 1.14V to 1.26V, falling threshold 0.94V to 1.06V) and do not leave it floating.
5 IN power_in Input pin for the 4.5V to 100V supply; decouple to GND with at least a 1µF ceramic capacitor.
6 LX output Inductor pin connected to the switching node of the inductor; keep the copper area on this node minimized to limit noise.
