                                      The SY20652 is a high efficiency 2MHz synchronous step-down DC/DC converter capable of delivering 2A current, which integrates an inductor into a compact 3×3×2mm QFN package. The SY20652 operates over a wide input voltage range from 4.5V to 23V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.


                                      SY20652 features adjustable soft-start time, enable control and power good indicator for system sequence control. The device also provides cycle-by-cycle current limit, short circuit protection and thermal shutdown protection for reliable operation.
