摘要:
A driving apparatus drives a mover arranged for feedback of a touch panel. A reference voltage generation unit generates a reference voltage having a signal waveform to be applied to the mover. A pulse modulator generates a PWM signal of which duty ratio is controlled by feedback so that a feedback voltage corresponding to a drive voltage to be applied to the mover approaches the reference voltage. A switching element of the DC/DC converter is turned ON/OFF by a PWM signal from the pulse modulator, so that an output voltage of the DC/DC converter is controlled, and a drive voltage corresponding to the output voltage is applied to the mover.
