... MIC2292/93 General Description The MIC2292 and MIC2293 are high frequency, Pulse Width Modulator (PWM) boost regulators optimized for constant- current, white LED driver applications. Because of their constant PWM switching frequencies of 1.6MHz and 2MHz, respectively, the MIC2292/93 can use the smallest external components, allowing designers to avoid sensitive IF bands in their RF applications ...

... 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 MIC2292/93 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 ...
