SY8891ARC

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.
