駆動回路、駆動装置及び画像形成装置
Document Type and Number:
Japanese Patent JP5460350
Kind Code:
B2
Abstract:
A driver circuit is used for driving a plurality of groups of switch elements connected between a power supply terminal (VDD) and a common terminal (IN). Each switch element includes anode connected to the power supply terminal (VDD), a cathode, and a gate. The anode is connected to the power supply and the cathode connected to a common terminal. The gate controls electrical conduction between the anode and the cathode. The driver circuit includes a switch circuit connected between the power supply terminal and the common terminal, and a driver circuit (41, 42, 43) into which a drive current (Iout) flows. The switch circuit is in parallel with the switch elements, and the switch circuit electrically connects or disconnects between the power supply terminal (VDD) and the common terminal (IN) in response to a control signal (DRV-ON) supplied thereto. A transmission line (70) having a specific characteristic impedance, connected between the common terminal (IN) and the driver circuit.
