Abstract: A circuit for restraining a shoot through current comprises a master selecting unit and a logic unit. The master selecting unit receives an input signal, and outputs first and second master selecting signals. The logic unit comprises first and second logic elements which generate first and second control signals for controlling two transistor switches connected in series. The first and second logic elements change the logic states of the first and second control signals according to the first and second master selecting signals. When the input signal is at a first logic level, the first logic element acquires a control privilege to change the logic state of the first control signal and trigger the second logic element to change the logic state of the second control signal. When the input signal is at a second logic, the second logic element acquires the control privilege.

Abstract: An LED driving circuit is used for dimming by switching between an operating current and a maintaining current or by voltage clamping of a source/drain of MOSFET that is coupled to the LED module. When the LED module is dimmed off, the voltage across the LED module can be kept at a value around a lighting threshold voltage of the LED module that is a minimum voltage for lighting the LED module. Therefore, a voltage difference between the drain and the source of MOSFET coupled to the LED module is smaller than that in the conventional arts. Hence, a withstand voltage of MOSFET can be reduced, and cost of the LED driving circuit as well as the power consumption of MOSFET can be lessened, thereby improving integral efficiency of the circuit.
