    Abstract: LED driving circuit includes a first current source, a second current source, a current sensing circuit, and a control circuit. The first current source, coupled in series with a heat dissipation resistor, provides a first current path to the LED string. The second current source, coupled in parallel with the serially coupled first current source and the heat dissipation resistor, provides a second current path to the LED string. The current sensing circuit is configured to sense a current sense signal representing a current flowing through the LED string. The control circuit is configured to control a current distribution of the first current path and a second current path in response to the current sense signal. When the current sense signal is greater than a threshold, a current flowing through the first current path is larger than a current flowing through the second current path.
