  • LED driver and an LED driving method
    Patent number: 10051710
    Abstract: An LED driver, comprising: an inductive switch mode converter having an inductive component (16,22), an LED output (30) for an LED load and a main converter switch (18) for controlling a current flowing through the inductive component; a sensor (32) for generating a sensor signal indicative of the output current or voltage provided to the LED output; a feedback element (34) which provides a feedback path for feeding back the sensor signal for control of the main converter switch (18); and a processing circuit (50) for processing the sensor signal which has been fed back, wherein the processing circuit is adapted to generate an output when there is no sensor signal so as to limit the current flowing through the main converter switch when no sensor signal is present.
