SY21288A
SY21288A is Synchronous Buck Converter manufactured by Silergy.
High Efficiency Fast Response, 8A, 24V Input Synchronous Buck Converter
General Description
The SY21288A 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 pseudoconstant frequency of 600kHz, to enable the use of small size inductor and capacitors. The SY21288A 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.
