Load driving circuit, liquid ejection device, and printing apparatus

摘要

A load driving circuit includes first storage elements charged by a power supply and a series storage element group constituting unit that switches the connection state between the first storage elements to constitute a series storage element group in which the first storage elements are connected in series. A second storage element charging unit charges a second storage element using the series storage element group. Switching is performed between first and second connection states to apply voltage to the load. In the first connection state, the charged second storage element and the series storage element group are connected to the load while the second storage element and the series storage element group are connected in series. In the second connection state, the series storage element group is connected to the load while the series connection between the second storage element and the series storage element group is broken.
