摘要： A network device adapted for sending a synchronization packet to a slave device. The synchronization packet includes a timestamp field and a correction field. The network device includes a counting circuit, a communication chip, and a processor. The counting circuit is configured to provide a calendar time TOD. The communication chip includes a first port, a second port, and a timestamp circuit which has a bit number N. The processor is coupled to the first port of the communication chip. The processor is configured to: obtain a remainder R according to the calendar time TOD and the bit number N; and write the calendar time TOD and the remainder R into the synchronization packet.

摘要： A power sharing device and method thereof are disclosed herein. The power sharing device includes a control unit, multiple regulators and multiple feedback circuits. Each regulator includes a first input terminal, a second input terminal and an output terminal. The control unit generates multiple pulse-width modulation signals. The first input terminal receives one of multiple input voltages. The second input terminal receives one of the pulse width modulation signals. The output terminal selectively outputs an output power. Each feedback circuit is coupled between the second input terminal and the output terminal of one of the regulators. The output terminals of the regulators are coupled to a load, and the regulators selectively output the output power one at a time and in rotation according to the input voltages and duty cycles of the pulse-width modulation signals.
