    摘要: The present disclosure provides methods and apparatus for fault protection for electronic devices (e.g., cold cathode fluorescent lamps). In one embodiment, a fault signal is detected and compared with a threshold to output a comparison signal. The comparison signal is then processed to generate a trigger signal, which triggers a fault control block once it satisfies certain fault conditions.
