Silergy SY8286ARAC QFN-20 Chip for Laptops
SY8286ARAC is a synchronous voltage converter (step-down/buck regulator) from Silergy Corp, used on laptop motherboards for powering and regulating the voltage of components. The component is made in a QFN-20 package and is intended primarily for professional electronics repairs.
The chip can be used as a replacement part in case of damage to the original voltage converter on the motherboard. Installation requires appropriate soldering equipment and experience in SMD electronics repairs.
Key features of the SY8286ARAC chip
- Manufacturer: Silergy Corp
- Marking: SY8286ARAC
- Series: SY8286
- Chip type: synchronous step-down converter (buck regulator)
- Package: QFN-20

What is a step-down converter used for?
Buck converters lower the input voltage to the value required by individual motherboard components, ensuring their stable power supply. Damage to such a chip can cause a lack of power to a specific section of the board, unstable laptop operation, or complete failure of the device to start.
Check the chip marking before purchase
Before ordering, the full marking of the chip on the motherboard being repaired should be compared. Different revisions and variants of converters may differ in electrical parameters, so the selection of a replacement should be preceded by careful verification.
We recommend selecting the chip based on the marking of the original component and the motherboard number, not solely on the laptop model.
Application
The SY8286ARAC QFN-20 chip is intended mainly for:
- laptop and electronics service centers,
- technicians dealing with motherboard repairs,
- professional SMD soldering stations.
Important: replacing a QFN-20 chip requires precise soldering. Before installation, make sure that the marking and version of the chip match the component on the board being repaired.
