SY8089A

TECH PUBLIC · DC-DC Converters · SOT-23-5

SY8089A from TECH PUBLIC, in a SOT-23-5. 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 on and do not float (VIH min 1.1V, VIL max 0.9V).
2 GND power_in Ground pin.
3 LX output Inductor pin; connect to the switching node of the inductor (voltage range -0.3V to VIN+0.3V).
4 IN power_in Input supply pin, 2.5V to 5.5V operating; decouple to GND with at least 22uF ceramic capacitor.
5 FB input Output feedback pin; connect to the center of the output resistor divider to set Vout=0.6*(1+R1/R2).
