Switching regulator with improved Dynamic response

摘要

A switching regulator having improved dynamic response to load variations includes a load compensation circuit coupled to the output terminal. The load compensation circuit supplies current to a load coupled to the output terminal when the output voltage is less than a first predetermined level and/or diverts current away from the load when the output voltage is greater than a second predetermined level. The load compensation circuit operates in this manner until the output voltage is between the first and second predetermined levels. The load compensation circuit responds faster to load variations than the switching regulator to accommodate sudden changes in the load demand.
