FR9885S6CTR FR9885S6 FR9885 CODE A9A31K SOT23-6

18V, 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 load current capability. At light load condition, the FR9885 can operate at power saving mode to support high efficiency and reduce power loss. The FR9885 fault protection includes cycle-by-cycle current limit, UVLO 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. Internal compensation function reduces external compensation components and simplifies the design process. In shutdown mode, the supply current is about 1μA. The FR9885 is offered in SOT-23-6 package, which provides a very compact system solution.
