Product Features 

The SY8286RAC (SY8286) is an advanced synchronous step-down DC-DC regulator designed by Silergy for laptops and high-performance power systems. Operating over a wide input voltage range from 4V to 23V, it flawlessly generates the required voltage outputs between 0.6V and 2.5V for the system. By featuring built-in main switch and synchronous switch MOSFETs with low RDS(ON) values (38/19 mΩ), it minimizes power dissipation (conduction loss). This compact IC delivers a 6A continuous output current and a 12A peak output current capacity for instantaneous loads, ensuring superior energy efficiency even under heavy loads. Thanks to its Instant PWM architecture, it provides an exceptionally fast transient response to load variations while operating at a 500kHz pseudo-constant frequency to optimize the sizes of external inductors and capacitors. Widely searched in the industry and on schematics by its BAA*** (or BAAxxx) marking code, this buck converter is a critical component in laptop motherboard repairs and features an internal soft-start to limit inrush current. With its compact QFN-20 (3x3 mm) package structure, it occupies minimal space on the PCB while providing maximum thermal dissipation.
