ABSTRACT:
An apparatus for supplying power to a load having a plurality of power requirements, including normal power requirements and transient power requirements, the apparatus comprising a switching regulator that satisfies the normal power requirements of the load, and an amplifier that supplements the regulator output of the switching regulator, to satisfy the transient power requirements of the load. The switching regulator circuit being less responsive to high frequency changes in the power requirement of the load, while the amplifier being less responsive to low frequency changes in the power requirements of the load. The combination of the switching regulator and the amplifier resulting in a transient tolerant apparatus for the supply of power to a dynamic load.
