摘要： PROBLEM TO BE SOLVED: To allow a stable and high-accuracy constant-voltage control at the time of no load or light load.SOLUTION: In a driving-signal generation circuit 24 that receives a PWM control signal and outputs a PWM driving signal, when a voltage Vb changes from H to L, a charging current flows into a capacitor 30 from a power-supply line 27 through a transistor TP2 and a resistor 29, so that the rising gradient of a voltage Vc decreases and inversion timing to H is delayed.

The providing of a delay circuit 31 narrows the H pulse width of the voltage Vc and can output an extra narrow on-pulse.

摘要： PROBLEM TO BE SOLVED: To provide a gate drive circuit capable of reducing a response time to the convergence of a gate voltage to a clamp value, without causing the increase of a circuit area and manufacturing cost.SOLUTION: When abnormality of an overcurrent flow occurs in a transistor Q11, an abnormality detection signal Sa becomes an H level, so that a switch S11 is switched on. In this state, when a potential difference between signal lines L13 and L12 rises to almost exceed a clamp value, a Zener diode D11 breaks down, and the most breakdown current thereof becomes the base current of an amplification transistor T12. A current amplified from the breakdown current by the amplification action of the amplification transistor T12 is supplied to the base of a clamping transistor T11. The clamping transistor T11 produces a collector current flowing between signal lines L11 and L12 in accordance with the supplied base current. By this, a potential difference between the signal lines L11, L12 is decreased.
