Abstract
A converter circuit, included in a power converter circuit, may generate a given voltage level on a regulated power supply node of a computer system. A control circuit may monitor a voltage level and assert a control signal in response to a determination that a regulation event has occurred. A boost converter circuit, included in the power converter circuit, may inject charge into to the regulated power supply node via a capacitor, in response to an assertion of the control signal.
Claims20
An apparatus, comprising:
- a first power converter circuit coupled to a regulated power supply node, wherein the first power converter circuit is configured to generate a given voltage level on the regulated power supply node;
- a second power converter circuit coupled to the regulated power supply node via a capacitor, wherein the second power converter circuit is configured to inject charge to the regulated power supply node in response to an assertion of a control signal;
- and
- a control circuit configured to assert the control signal in response to a detection of a regulation event associated with the regulated power supply node.
