摘要：
Methods and circuits are described herein which may be used to improve the unloading transient response of a DC-DC converter. In some embodiments the transient response may be improved by improving the way MOSFET switches in the buck converter are controlled at the point in time when a current transient is detected, and subsequently during the transient, in such a way that the impact of the current transient is mitigated. In other embodiments an auxiliary current source is used to provide rapid transient response required by the overall power converter, leaving the main portion of the DC-DC converter to provide long term stability.
