... If the LEDs are disconnected from the circuit case an LED fails open, the sense resistor will pull the FB pin to ground. This will cause the MIC2287 to switch with a high duty-cycle, resulting in output overvoltage. This may cause the SW pin voltage to exceed its maximum voltage rating, possibly damaging the IC and the external components ...
