FR9889经典降压芯片,代理含税FR9889


Description
  The FR9889 is a synchronous step-down DC/DC converter that provides wide 4.5V to 23V input voltage range and 3A continuous load current capability. At light load condition, the FR9889 can operate at power saving mode to support high efficiency and reduce power lose.
  The FR9889 fault protection includes cycle-by-cycle current limit, UVLO, output overvoltage protection and thermal shutdown. The 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 FR9889 is available in a SOP-8 exposed pad package, which provides good thermal conductance.
