Abstract
A voltage converter having a controller capable of maintaining stable operation of a voltage converter over multiple modes of operation. The voltage converter provides a feedback signal to an error signal generator. One or more controllers, which are selectively established as part of the feedback loop, process the error signal to generate a voltage converter charging cycle control signal. A pulse width modulator may be utilized to generate a voltage converter switch control signal that controls the charge cycle. A detector or comparator monitors one or more aspects of operation of the control circuit or the voltage converter to detect changes in the mode of operation. Upon detection of a change, the detector or comparator generate a multi-mode control signal to selectively switch one or more sub-controllers into or out of the feedback loop to thereby maintain desired stability, loop bandwidth, and response time.
