Patent number: 6294903Abstract: A switching power supply of a step-down chopper system, which is capable of reducing power consumption and unused power supply to the output. A voltage supplied to an input main terminal is turned ON/OFF by a switching device controlled by a control circuit, and outputted to an output main terminal through a conversion circuit. An output voltage detecting circuit detects the output voltage at the output main terminal, and according to the state of the output voltage detected, a feedback circuit is controlled, so that the ON/OFF control over the switching device by the control circuit is paused (or stopped). Thus, the switching device oscillates or is paused (stopped) according to the output voltage.Type: GrantFiled: April 11, 2000Date of Patent: September 25, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Tetsuji Yamashita, Yoshihiro Mori, Yuji Yamanishi, Yoshiaki Hachiya

Patent number: 6005350Abstract: An EL driving apparatus is composed of a display portion, a photodiode as changing means for changing a reference voltage for controlling an increased voltage based on ambient brightness and a control portion for controlling the timing of discharging based on the reference voltage. The control portion has a comparator for comparing a specified peak value obtained by reducing the increased voltage generated by voltage increasing means with the reference voltage generated from within. The increased voltage is inputted to the control portion. The increased voltage is reduced to provide a detect voltage that can be inputted to the comparator. The comparator has a positive-phase input terminal for receiving the detect voltage and a negative-phase input terminal for receiving the reference voltage produced at a connection point between a constant current source and a resistor connected in series to each other.Type: GrantFiled: February 23, 1998Date of Patent: December 21, 1999Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshiaki Hachiya, Yuji Yamanishi, Yuji Ueno
