SY9329C Datasheet | Silergy

High Efficiency, 38V Maximum Input Single Inductor Synchronous Step Up/Down Regulator General Description The SY9329C 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 SY9329C 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 pact QFN4×4-32 package.
