Overview

SY9329C is a high-voltage synchronous buck-boost converter. The device operates over a wide input voltage range of 4V to 28V, with a maximum average inductor current capability of 10A. Four integrated low R_DS(ON) switches minimize conduction losses. The SY9329C incorporates comprehensive protection features, including output overcurrent/short-circuit protection, overvoltage protection, and thermal shutdown, ensuring reliable operation. The device is housed in a compact QFN4×4-32 package.
