摘要：
A DCR sense scheme is provided to sense the inductor current of a COT power converter. The DCR sense is implemented by using the direct current resistance of the output inductor of the COT power converter, and thus eliminates the ESR limitations on the type of output capacitors for stability concern. A quick response mechanism is further incorporated in the COT power converter to speed up the transient response of the COT power converter.
