SY8816DFC

Silergy Corp · DC-DC Converters · DFN-8(2x2)

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).
