The FR9886 is a synchronous step-down DC/DCconverter that provides wide 4.5V to 23V inputvoltage range and 2.5A continuous load currentcapability.The FR9886 fault protection includes cycle-by-cyclecurrent limit, UVLO, output overvoltage protectionand thermal shutdown. The adjustable soft-startfunction prevents inrush current at turn-on. Thisdevice uses current mode control scheme whichprovides fast transient response. Internalcompensation function reduces externalcompensation components and simplifies the designprocess. In shutdown mode, the supply current isless than 1μA.The FR9886 is available in a SOP-8/SOP-8 exposedpad package, and provides good thermalconductance.
