    摘要: A differential driving circuit for powering a light source is disclosed. The differential driving circuit includes a first set of switches and a second set of switches. A first current from a power source flows through the first set of switches to charge a first energy storage element when the first set of switches are turned on. A second current from the first energy storage element flows through the second set of switches to power the light source when the second set of switches are turned on. The differential driving circuit further includes a second energy storage element coupled to the light source in parallel and for providing a differential voltage to the light source.

    摘要: In one embodiment, a controller includes a first comparator, a second comparator and a control unit coupled to the first and second comparators. The first comparator is operable for comparing a first sense signal indicative of an output current flowing through an energy storage component of the power converter with a first threshold, and for generating a first comparison signal. The second comparator is operable for comparing a second sense signal indicative of the output current with a second threshold and for generating a second comparison signal. The control unit is operable for turning a switch of the power convertor on and off according to the first and second comparison signals. The energy storage component is coupled to a power source for storing energy from the power source if the switch is turned on, and is decoupled from the power source for releasing stored energy to a load if the switch is turned off.
