Description

The SY21612C is a high voltage synchronous Buck-Boost converter. The device operates over a wide input voltage range from 4V to 28V with 10A maximum average inductor current capability. The four-integrated low RDS(ON) switches minimize the conduction loss. 
The SY21612C includes full protection features, such as output over current/short circuit protection, over voltage protection and thermal shutdown for reliable operating. 
The device is available in compact QFN4×4-32 package.
