Abstract
An IC incorporating a multiphase voltage converter with synchronized phase shift including a phase shift pin, a frequency select pin, a master clock pin, and a voltage regulator. The phase shift pin is coupled to a first voltage for a master mode or a first resistor for a slave mode. The frequency select pin is coupled to one of a second voltage and a second resistor. The master clock pin provides a master clock signal or receives an external clock signal. The IC provides the master clock signal at a frequency determined by the second resistor or otherwise at a default frequency. The voltage regulator operates in the slave mode at a phase shift relative to the external clock signal based on the first resistor and the second resistor or based on the first resistor and a default resistance if the second voltage is coupled.
