Power supply and related circuits

A method comprising:

• configuring a controller circuit to:
• simultaneously control both a voltage regulator circuit and a dynamic power supply circuit, the dynamic power supply circuit having a faster response time to convey power to a load than the voltage regulator circuit;
• while the dynamic power supply circuit is disabled from supplying power to a load, monitor a voltage produced by the voltage regulator circuit that is used to supply power to the dynamic load;
• initiate activation of the dynamic power supply circuit in parallel with the voltage regulator circuit to selectively supply additional power to the dynamic load depending on a magnitude of the monitored voltage;
• and
• enable repeated ON and OFF switching of a switch in the dynamic power supply circuit to convey power to the load at a same time that a switch in the voltage regulator circuit is switched ON to supply power through an inductor to the load.

• in response to detecting a drop in the monitored voltage while the dynamic power supply circuit is disabled from supplying power to the load, initiating activation of the dynamic power supply circuit to provide power to the load;
• enabling repeated ON and OFF switching of a switch in the dynamic power supply circuit to convey power to the load at a same time that a switch in the voltage regulator circuit is switched ON to supply power through an inductor to the load.
