  • Transistor switch control circuit
    Patent number: 8552768
    Abstract: A synchronous driving circuit in the arts may cause a short through pheromone when a duty cycle of a duty cycle control signal is too short. The present invention sets a delay time with a suitable period when the duty cycle of the duty cycle control signal is too short to avoid the short through phenomenon.
    Type: Grant

  • Transistor module and transistor driving module
    Patent number: 8368433
    Abstract: The present invention discloses a transistor driving module, coupling to a converting controller, to driving a high side transistor and a low side transistor connected in series, wherein one end of the high side transistor is coupled to an input voltage and one end of the low side transistor is grounded. The transistor driving module comprises a high side driving unit, a low side driving unit, a current limiting unit and an anti-short through unit. The high side driving unit generates a high side driving signal to turn the high side transistor on according to a duty cycle signal, and the low side driving unit generates a low side driving signal turn the low side transistor on according to the high side driving signal. The current limiting unit is coupled to the high side transistor and the high side driving unit, and generates a current limiting signal when a current flowing through the high side transistor higher than a current limiting value.
