Abstract
An asymmetric multi-converter power supply including a first converter and a second converter coupled to provide power to an output node. A control circuit is coupled to the second converter and is configured to selectively enable the second converter depending upon a voltage at the output node. The control circuit may be configured to enable the second converter only in response to determining that the voltage at the output node is not within a predetermined range. Alternatively, the first converter is configured to provide power through a first series inductor and the second converter is configured to provide power to the output node through a second series inductor. The second series inductor having a smaller inductance than the first series inductor. Additionally, the second converter may be characterized by a transient response time that is faster than a transient response time of the first converter.
