Description    The FR9833 is a synchronous step-down DC/DC converter that provides wide 6V to 32V input voltage range and 3A continuous load current capability.    The FR9833 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 1μA.    The FR9833 is available in an SOP-8 (exposed pad) packages, provides a very compact system solution and good thermal conductance. It is RoHS compliant and 100% lead (Pb) free.
