... PWM control. These devices include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc. AP1513 provides low-ripple power, high efficiency, and excellent transient characteristics. The PWM control circuit is able to vary the duty ratio linearly from 100%. This converter also contains an error amplifier circuit as well as a soft-start circuit that prevents overshoot at startup ...

... Function Description PWM Control The AP1513 consists of DC/DC converters that employ a pulse-width modulation (PWM) system. In converters of the AP1513, 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 ...
