摘要： According to one embodiment, a management circuit for a portable device includes an input terminal, a first step-up converter, a first step-down converter, and a second step-down converter. The input terminal is coupled to receive a supply voltage from a power supply. The first step-up converter, coupled to the input terminal, selectively converts the supply voltage to a boosted voltage. The first step-down converter, coupled to the first step-up converter, selectively provides a first output power voltage to a first radio frequency (RF) module. The second step-down converter, coupled to the first step-up converter, selectively provides a second output power voltage to a second radio frequency (RF) module. The first step-up converter performs the conversion of the supply voltage when the supply voltage is under a threshold voltage.

摘要： An operating method for an integrated interface of a PDA and a wireless communication system includes the following steps. Firstly, when the wireless communication system starts to operate from a standby mode, a state signal is transmitted from the wireless communication system to the PDA. Then, if the PDA receives the state signal when the PDA is in a sleep state, the PDA is wakened and an input source of an audio element inside the PDA is switched to the wireless communication system. An electromagnetic wave signal is received by a wireless communication element and converted into audio data. Afterwards, the audio data is transmitted from the wireless communication system to the PDA and outputted by the audio element.
