FR9885 Synchronous Step-Down DC/DC Converter

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-c.
