Datasheet Summary
High Efficiency Fast Response, 98% Duty, 8A, 30V Input Synchronous Buck Converter
General Description
The SY21232 is a high efficiency synchronous buck converter operating over a wide input voltage range of 4.5V to 30V 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 500kHz, to enable the use of small size inductor and capacitors. The SY21232 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.
