描述 Description

The FR9761 is a 1.4MHz 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 FR9761 is available in a MSOP-10 package, which provides a very compact system solution and good thermal conductance.
