2A, 500KHz Synchronous Step-Down DC/DC Converter Description The FR9885 is a synchronous step-down DC/DC converter that provides wide 4.5V to 18V input voltage range and 2A peak load current capability. At light load condition, the FR9885 can operate at PSM mode to support high efficiency and reduce power loss. The FR9885 fault protection includes cycle-by-cycle current limit, UVLO, output overvoltage protection and thermal shutdown.The internal soft-start function prevents inrush current at turn-on. This device uses current mode control scheme which provides fast transient response.
