FR8018 23V, 4A, 500KHz Synchronous Step-Dow85nT DC/DC Converter Description 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. Besides, adjustable soft-start or internal soft-start function prevents inrush current at turn-on. This device uses current mode control scheme which provides fast transient response. Internal compensation function reduces external compensator components and simplifies the design process.
