ABSTRACT:
A predetermined positive output voltage to be obtained by raising an input power supply voltage is outputted by switching a switch connected in series with a coil in a switching power supply circuit. On the other hand, in a negative output voltage generating circuit, a negative output voltage, which is equal in magnitude to a predetermined voltage, is generated according to a setting voltage, which is lower than the positive output voltage by the predetermined voltage, and a voltage that changes with switching.
