產(chǎn)品介紹

Product index

The FR9855 is a synchronous step-down DC/DC converter with fast constant on time (FCOT) mode control. The device provides 4.5V to 18V input voltage range and 5.5A continuous load current capability. Operation frequency depends on Input and output voltage condition. At light load condition, the FR9855 can operate at power saving mode to support high efficiency and reduce power loss.
