摘要： A multi-channel regulator system includes serially connected PWM integrated circuits, each of which determines a PWM signal for a respective channel to operate therewith, and individually controls its operation mode according to whether or not an external clock is detected. Therefore, each channel will not be limited to operate under a constant mode and could become a master channel or a slave channel. Additionally, each of the PWM integrated circuits generates a phase shifted synchronous clock for its next channel during it is enabled, and thus all the channels operate in a synchronous but phase interleaving manner.

摘要： A level shift circuit includes an input stage and an output stage coupled to each other by two nodes. The input stage changes the voltages on the nodes according to an input signal, and the output stage determines an output signal according to the voltages on the two nodes. In a transition state, the input stage provides a large current to charge or discharge the first node or the second node so as to quickly change the voltage thereon. In a steady state, the input stage lowers the current so as to reduce power consumption.
