摘要： A power converter controller includes a storage time reference circuit to generate a storage time reference signal in response to an input voltage signal. A first comparator generates a collector off signal in response to a current sense signal of a BJT and a collector off reference threshold signal. A storage time regulator circuit generates a base off reference threshold signal in response to the storage time reference signal and the collector off signal. A second comparator generates a base off signal in response to the current sense signal and a base off reference threshold signal. A driver circuit controls switching of the BJT in response to an output voltage signal, discontinues charging a base terminal of the BJT in response to the base off signal, and starts discharging the base terminal of the BJT in response to the collector off signal during a switching cycle of the BJT.

摘要： A circuit including a voltage-controlled transistor to be switched. A first transistor is switched on, mediated by a control signal, and a first current flows through a series circuit and starts to subject a control input of the voltage-controlled transistor to charge reversal. The first current brings about a first potential shift at a connecting node. A second transistor is switched on by this first potential shift and a second current therefore flows through the switching path of the second transistor into the control input of the first transistor, which amplifies the first current. The increasing charge reversal of the control input of the voltage-controlled transistor brings about a second potential shift at the connecting node, the second transistor is switched off by this second potential shift, and the first transistor remains switched on, however, and holds the voltage-controlled transistor in its new switching state.

摘要： Techniques and circuits for high speed switching of transistors are provided. These techniques and circuits switch an output device while varying the drive current to the output device in proportion to the output current through the output device. In addition, these techniques and circuits provide a switching circuit with substantially no quiescent currents. This is accomplished by sampling the output current conducted by the output device and using the sample as a signal to drive either the output device fully ON or to switch the output device fully OFF.

摘要： The present invention discloses an output circuit, by which it is possible to reduce power consumption while maintaining maximum voltage value to be outputted at high level. In this output circuit, a charge-and-discharge circuit uses a terminal voltage Vc of a capacitor as a trapezoidal wave voltage, and a drive circuit drives an output transistor based on the terminal voltage Vc, and a voltage Vo equal to the terminal voltage Vc is outputted to the load. A voltage detection circuit detects an emitter voltage (VcnullVF) of the transistor and generates an electric current proportional to the terminal voltage Vc. This electric current is turned to a base current of the output transistor via a variable current circuit. Therefore, a base current proportional to the output voltage Vo is supplied to the output transistor.
