FR9888A

Description

The FR9888A is a synchronous step-down DC/DC converter that provides wide input voltage range and 3A continuous load current capability.  The FR9888A fault protection includes cycle-by-cycle current limit, UVLO, output overvoltage protection and thermal shutdown. The 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 FR9888A is available in a SOP-8 Exposed Pad package, and provides good thermal conductance.
