Power Converter with Transient Processing Capability

Abstract

Transient processing mechanisms for power converters. Error generation circuitry in a power converter may generate an error signal based on the difference between a power converter output voltage and a reference voltage. Transient detection circuitry may detect whether the error signal exceeds at least a first threshold. If the first threshold is exceeded, timing control logic may generate a low band correction pulse to adjust the power converter output voltage, and thereby adjust the error signal to a level within the first threshold. If the error signal exceeds a second threshold, the timing control logic may generate a high band correction pulse to adjust the power converter output voltage, and thereby adjust the error signal to a level within the second threshold. The timing control logic may initiate a low band blanking period following the low band correction pulse and high band blanking period following the high band correction pulse.
