<P>PROBLEM TO BE SOLVED: To provide an electronic device provided with a power supply circuit which can be safely stopped even when a feedback coil is broken. <P>SOLUTION: An IC monitors a voltage value of a feedback coil through a first terminal and outputs a drive signal for driving a switching element in accordance with the voltage value of the feedback coil. The electronic device includes voltage lowering means which is configured to latch the IC when a voltage value generated at a second terminal is a predetermined threshold or less, and lowers a voltage applied to the second terminal when a voltage supplied from the feedback coil is a predetermined value or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
