摘要： Two systems consisting of an on-off control section corresponding to the saturation drive system and a constant voltage control section corresponding to the constant voltage drive system are provided as a circuit for controlling the conduction state of a transistor QP11 provided at the output section. The constant voltage unit comprises an operational amplifier A1, which monitors the output voltage Vout and feedback-controls the gate voltage of QP11. On the other hand, the on-off control section delivers a control signal for turning on and off QP11 corresponding to an input signal input to IN-U through inverters 40 and 42. Switches 46 and 48 for selectively applying the output from the control unit of either one of these two systems are provided to select the switch to be turned on based on a mode signal input to SW. This configuration enables the realization of different drive systems and restricts increase in circuit size while commonly using the output unit configured with comparatively large transistors. In addition, since the saturation drive system can be realized without depending on feedback control, high control responsiveness is secured to appropriately perform operation at high frequencies such as switching operations by PWM control.

摘要： In CMOS processing, there may be a case in which a resistance element, such as a poly-silicon resistance, or the like, may be formed which has negative temperature characteristics, that is, the characteristics opposite from the characteristics of a typical resistance element. In a constant current circuit using this resistance element, a constant current output less affected by the influence of varying temperature is obtained. To one of the paths of a current mirror circuit from which a constant current is extracted, a serial connection circuit comprising a transistor Q1 for flowing a current I1 having positive temperature characteristics, a resistance element R1 and a bipolar transistor Q6 is connected. Further, in parallel to this serial connection circuit, a temperature compensation circuit comprising a transistor Q8 for flowing a current I2 having negative temperature characteristics and a resistance element R2 is connected. A constant current output based on the sum current I of the currents I1 and I2 is obtained. In this manner, an output less affected by the influence of varying temperature is obtained.
