SY21286A Datasheet | Silergy

High Efficiency Fast Response, 98% Duty, 6A, 24V Input Synchronous Buck Converter General Description The SY21286A 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 600kHz, to enable the use of small size inductor and capacitors. The SY21286A also provides 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.
