A wireless presentation system includes a first wireless input element, a second wireless input element and a wireless receiving and processing host. A pairing method for use in the wireless presentation system includes the following steps. The wireless receiving and processing host generates a first identification code, and if the first wireless input element is present, issues the first identification code to the first wireless input element for storage, so that a pairing relation therebetween is established by the first identification code. The wireless receiving and processing host automatically generates a second identification code after the first identification code is issued, and if the second wireless input element is present, issues the second identification code to the second wireless input element for storage, so that the pairing relation therebetween is established by the second identification code.

A power supply topology with pulse width modulation frequency control allows the use of an inductor with higher inductance in a converter. By controlling the switching frequency of the pulse width modulation signal, the inductor can achieve high efficiency during a light load condition and is also suitable for a heavy load condition.
