Description

  The FR9832 is a synchronous step-down DC/DC converter that provides wide 6V to 32V input voltage range. There are two packages, SOP-8 & SOP-8 (Exposed Pad), to support 2A continuous output current.

  The FR9832 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 FR9832 is available in SOP-8 and SOP-8 (exposed pad) packages. It is RoHS compliant and 100% lead (Pb) free.
