Microprocessor Fast Load Current Changes
The microprocessors and SoC Integrated Circuits impose very demanding large and fast load current changes of 10A/usec to 50A/usec yet requiring ultra small transient voltage overshoot to settle very quickly. This is currently handled by up to 12 synchronous buck converter operating in parallel at 5MHz from 12V input resulting in poor efficiency, large size and high cost! This demand is currently met by third party vendors using the same multistage buck approach consisting of over 40 power management companies slicing the 10 billion dollar market among them by providing 12V to 2V . . .
