摘要
A load transient compensator and method of operating the load transient compensator for reducing the transient response time to a load capable of operating at either of several consumption levels when the load changes its power consumption level. The load transient compensator has a comparator having an output connected to an input of an upper driver and of a lower driver with the output of each of the driver being connected to a gate of a power transistor. When the load is in sleep mode and is about to start being accessed, the upper driver is turned on to turn on its associated transistor to supply additional current to the load, regulated by the comparison circuit. When the load is in the power up mode and it is about to stop being accessed, the lower driver is turned on to turn on its associated transistor to drain current supplied to the load by a supply, regulated by the comparison circuit. This allows a quicker response to the large changes in current required by the load when the load is changing its level of power consumption without greatly increasing the cost of the system containing the load and without compromising the stability of the system.
