Capacitive load drive circuit and plasma display apparatus

摘要

A low-cost capacitive load drive circuit, in which a reference voltage, a first voltage, and a second voltage are supplied to a capacitive load, and a plasma display apparatus using it, are disclosed. The capacitive load drive circuit comprises a reference voltage switch (SWCD) the breakdown voltage of which is properly adjusted, a first switch (SWCU), a reference voltage phase adjusting circuit (13), and a first phase adjusting circuit (11), and malfunctions due to the difference in switching characteristics can be prevented from occurring even when devices of different breakdown voltages are used.
