APE3061, the pulse width varies in a range from 0 to 85%, according to the load
current. The ripple voltage produced by the switching can easily be removed through a
filter because the switching frequency remains constant. Therefore, APE3061 provide
a low-ripple power over broad ranges of input voltage and load current.
