fitipower integrated technology lnc. FR9886 85T 23V, 2.5A, 340KHz Synchronous Step-Down DC/DC Converter Description The FR9886 is a synchronous step-down DC/DC converter that provides wide 4.5V to 23V input voltage range and 2.5A continuous load current capability. The FR9886 fault protection includes cycle-by-cycle current limit, input UVLO, output over voltage protection and thermal shutdown. Besides, adjustable 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 less than 1uA.
