Digital DC/DC converter with SYNC control |
摘要 |
A power converter is disclosed for receiving an input voltage and converting it to a DC output voltage at a different voltage level than the input voltage. It includes a switching power converter for receiving the input voltage on an input and converting the input voltage to an output as the DC output voltage in response to pulse control signals. A switching controller is provided for generating the pulse control signals during a switching cycle and a processor controls the switching controller to define the length and initiation of the switching cycle. A communication interface interfaces with a first data communication bus for receiving data therefrom and with a second communication bus for receiving timing information therefrom. The processor and the switching controller operate in either a first operating mode to control the switching controller and the generation of the pulse control signals independent of timing information, or in a second operating mode to control the timing of the generation of the pulse control signals generated by the switching controller in response to timing information received from the communication bus.
