Function Description
PWM Control
The AP1511 consists of DC/DC converters that employ a pulse-width modulation (PWM) system. In converters of the AP1511, the
pulse width varies in a range from 0 to 100%, 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, these converters provide a low-ripple power over
broad ranges of input voltage and load current.
