  • Circuit for controlling current to light-emitting diode (LED)
    Patent number: 8912798
    Abstract: A current controlling circuit comprises a DC power source, an inductor, a N-channel Metal Oxide Semiconductor (NMOS), one or more LEDs connected in series, a first resistor and a switching arrangement. The positive terminal of the DC power source is connected to the inductor in series. The series of LED is connected in series with the inductor and the first resistor. According to an embodiment the switching arrangement comprises a second resistor, a first switch and a second switch. The second resistor is connected in series with the second switch and connected in parallel with the first switch. The switching arrangement is connected in series with the first resistor and the negative terminal of the DC supply.
