Datasheet in PDF for the SY8003ADFC, with C178236 in the name, a number that resembles an LCSC part code. The SY8003 is a Silergy synchronous step-down converter often used for low-voltage rails on laptop boards. Technicians use the sheet for the pinout, enable and feedback pins, typical application circuit and output voltage formula when diagnosing a missing rail or a shorted regulator. Check the package marking on the board against the datasheet before substituting a part.
