FR9886C中文资料Buck DC-DC数据手册Fitipower规格书

描述 Description

The FR9886C is a synchronous step-down DC/DC converter that provides wide 4.5V to 21V input voltage range.
There is SOP-8 pacakge to support 2A/2.5A continuous output current.  The FR9886C
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 FR9886C is available in SOP-8 package.  It is RoHS compliant and
100% lead (Pb) free.
