Abstract
Methods and circuits for power supply arrangement and control are disclosed herein. More specifically the application relates to a control method and a controller for a DC-to-DC converter, such as a synchronous Buck converter, which implements a transient detection scheme together with response generation to allow the converter to recover from a positive and/or negative load current step in the robust way, with low undershoot/overshoot at the output voltage. The control method may be implemented by either an analog or a digital circuit. The controller may be integrated with existing controller schemes (such as voltage-mode controllers) to provide superior dynamic performance during large-signal transient conditions while providing stable operation during steady state conditions. The methods and circuits provided herein are applicable to Buck converters and Buck-derived converters such as forward, push-pull, half-bridge, and full-bridge converters.
