FR8018 Overview
The FR8018 is a synchronous step-down DC/DC converter that provides wide 4.5V to 23V input voltage range and 4A continuous load current capability. At light load condition, the FR8018 can operate at PSM mode to support high efficiency and reduce power loss. The FR8018 fault protection includes cycle-by-cycle current limit, UVLO and thermal shutdown.
