SY8816DFC from Silergy Corp, in a DFN-8(2x2). 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 | EN | input | Enable control: pull high to turn the regulator on (EN rising threshold 1.2 V, falling threshold 0.4 V); do not leave it floating. |
| 2 | IN | power_in | Power input pin; supply range is 2.75 V to 6.0 V (absolute maximum 6.5 V). |
| 3 | LX | power_out | Inductor pin; connect to the switching node of the inductor (absolute maximum 6.5 V). |
| 4 | GND | power_in | Ground pin. |
| 5 | GND | power_in | Ground pin. |
| 6 | LX | power_out | Inductor pin; connect to the switching node of the inductor (absolute maximum 6.5 V). |
| 7 | PG | output | Power good indicator: open-drain output that becomes high-impedance when the output exceeds 90% of the regulation point and is low otherwise. |
| 8 | FB | input | Output feedback pin; connect to the center point of the output divider, with VOUT = 0.6 × (1 + R1/R2) and VREF of 0.6 V (0.591 V to 0.609 V). |
