Datasheet Summary
High Efficiency, Fast Response, 6A, 28V Input Synchronous Buck Converter
General Description
The SY21286 is a high efficiency synchronous buck converter operating over a wide input voltage range of 4.5V to 24V 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 pseudoconstant frequency of 500kHz, to enable the use of small size inductor and capacitors. The SY21286 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.
