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. |
