Abstract

PURPOSE:To improve conversion efficiency, by making ON/OFF control of push-pull type switching transistors alternately through a timing circuit connected with an oscillation circuit. CONSTITUTION:An output stage constituting a booster circuit comprises first and second PNP, NPN switching transistors(Tr) 11, 12. A capacitor 13 is connected to the joint P between the first and second Tr 11, 12 and charged by a power source Vdd through a diode 14 while discharged through a diode 15. Voltage boosted through charge/discharge of the capacitor 13 is taken out through a capacitor 16 from an output terminal 17. At this time, base signals are fed from a timing circuit 18 to respective bases of the first and second Tr 11, 12 so as to carry out ON control alternately. Consequently, Tr 11, 12 can be driven efficiently.
