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. |
