Abstract
A driver circuit for switching an output voltage (Vout) at an output terminalby using diode bridgesandincludes a first current mirror circuitfor letting flow a first balance current Iand letting flow a first transition current Iobtained by adding a first stationary current to a product of the first balance current Iand a predetermined multiplier when switching from the low level to the high level, and a second current mirror circuitfor letting flow a second transition current Iobtained by adding a second stationary current to a product of the second balance current Iand a predetermined multiplier when switching from the high level to the low level. As a result, the power dissipation in the stationary state is reduced without lowering the slew rate at the time when switching the output voltage.
