... Application Information Typical Application 1.8V-5.5V OFF 4.7µF Setting Current Limit The FPF2165R have a current limit which is set with an external resistor connected between ISET and GND. This resistor is selected by using the following equation 340 LIM SET The table below can be used to select RSET. A typical application would be the 500mA current that is required by a single USB port ...
