FR9710中文资料Buck DC-DC 数据手册Fitipower规格书

描述 Description

The FR9710 is a 380KHz step-down DC/DC converter that provides wide 4.75V to 23V input voltage range and 2A continuous load current capability. Fault protection includes cycle-by-cycle current limit, input UVLO and thermal shutdown. Besides, adjustable soft-start function prevents inrush current at turn-on. This device uses current mode control scheme that provides fast transient response. In shutdown mode, the supply current is about 10μA. The FR9710 is available in an SOP-8 package, which provides a very compact system solution and good thermal conductance.
