SYSTEM AND METHOD FOR CURRENT PULSE MATCHING TECHNIQUE IN A SWITCHED MODE POWER CONVERTER

摘要

The invention provides a circuit in a switched mode power supply converter, and method of controlling a circuit. The circuit comprises a current pulse matching circuit configured to negate output voltage disturbance/noise during switching operation of a power conversion. The current pulse matching circuit input is driven by, or from, a power converter switch node of the switched mode power supply converter. The current pulse matching circuit comprises a rate-of-voltage change detection circuit driven by the power converter switch node.
