The SY83088A1 is a high efficiency synchronous buck converter operating over a wide input voltage range of 4V to 24V and capable of delivering up to 8A current. It integrates low RDS(ON) top and bottom MOSFETs to minimize the conduction loss. It operates at a pseudo-constant frequency of 600kHz, to enable the use of small size inductor and capacitors. The SY83088A1 also integrates a bypass switch which allows the VCC to be powered by external 3.3V power supply, further reduce the power consumption of the entire system.
