Abstract: A multi-phase switch mode, voltage regulator has a transient mode portion in which a phase control output is coupled to one or more control inputs of one or more switch circuits that conduct inductor current through one or more transient phase inductors, from amongst a number of phase inductors. A slew mode control circuit detects a high slope and then a low slope in the feedback voltage and, in between detection of the high slope and the low slope, pulses the phase control output of the transient mode portion so that the switch circuit that conducts transient phase inductor current adds power to, or sinks power from, the power supply output. Other embodiments are also described.

Abstract: An electronic device includes a die, one or more power stages, and one or more sensors electrically coupled to the one or more stages and to determine data associated with a temperature of the die. The electronic device includes one or more off-die power stages external to the die and processing circuitry configured to cause the one or more off-die power stages to activate based on the data indicating that the temperature is greater than a temperature threshold.
