描述 Description

The FR9888C is a synchronous step-down DC/DC converter that provides wide 4.5V to 23V input voltage range and 3.5A continuous load current capability. The FR9888C 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. In shutdown mode, the supply current is less than 1μA. The FR9888C is available in an SOP-8 (Exposed Pad) package, provides a very compact system solution and good thermal conductance.
