The SY8386T is a high efficiency synchronous buck converter operating over a wide input voltage range of 4V to 25V and capable of delivering up to 6A current. It integrates low RDS(ON) top and bottom MOSFETs to minimize the conduction loss. It operates at a pseudo-constant frequency of 660kHz, to enable the use of small size inductor and capacitors. The SY8386T also integrates a bypass switch which allows the VCC to be powered by external 3.3V power supply and further reduces the power consumption of the entire system.
