ABSTRACT:
A device of pulse width modulation type for load drive according to the present invention includes a first output unit (3) that applies a first output signal (e) to a load (5) in response to a first drive timing signal (c), a second output unit (4) that applies a second output signal (f) to the load (5) in response to a second drive timing signal (d), a signal converter (1) that converts a drive input signal (a) into a parallel signal (b), the drive input signal indicating time information allowing a potential difference to be generated across the load (5), and a drive timing generator (2) that generates the first and second drive timing signals (c, d) in response to the parallel signal (b), the load (5) being driven by increasing and reducing pulse widths of the first and second output signals (e, f).
