Patent ID: 8400125

Claim:
A method of controlling a multiphase power converter including a plurality of sub-converters and a control circuit including a plurality of counters, each counter having a controllable count state different from the other counters, and each counter associated with a different one of the plurality of sub-converters, each controllable count state including a count represented by an integer, the method comprising: generating a reference signal representing a desired output of the power converter; determining if a relationship between the reference signal and a prior value of the reference signal satisfies a first condition; similarly changing the controllable count state of each of the plurality of counters if the first condition is satisfied; comparing the reference signal to a current state of each of the plurality of counters to determine for each counter whether a second condition is met; and for the sub-converters associated with the counters for which the second condition is met, generating a power switch control signal.
