Silergy Corp · DC-DC Converters · SOT-563-6
SY8891ARC from Silergy Corp, in a SOT-563-6. 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 | FB | input | Output feedback pin, connected to the center of the output resistor divider to set VOUT = 0.6 × (1 + RH/RL), with feedback reference VREF of 0.591 V to 0.609 V (0.6 V typical). |
| 2 | GND | power_in | Ground pin. |
| 3 | VIN | power_in | Input supply pin, decoupled to GND with at least a 10µF ceramic capacitor; the recommended supply input range is 2.5 V to 5.5 V. |
| 4 | LX | output | Inductor pin connected to the switching node of the inductor; LX voltage is rated -0.3 V (tested to -3 V for under 20 ns) to 6.0 V (tested to +7 V for under 20 ns). |
| 5 | EN | input | Enable control: pull high to turn the regulator on (VEN,H 1.2 V minimum, VEN,L 0.4 V maximum) and do not leave it floating. |
| 6 | PG | output | Power good indicator, an open-drain output that goes low when the output is below 90% or above 120% of the regulation voltage and requires a pull-up resistor to the input. |
