levels. The connectivity between the individual levels has to abide by the laws of electronics, meaning that operating frequency and

trace resistance result in rather high impedances which are putting a ceiling on the real world switching capabilities even if all

components used are capable of running much faster.

A possible workaround is to integrate the control circuitry and the driver chips into the same IC, a design recently pioneered by

OnSemiconductors. The lack of traces allows much faster regulation by means of mechanisms like early cycle termination so that

effectively, the integrated 2 phase design is functionally roughly equivalent to a standard four-phase design. It certainly speaks for

ASUS to see the OnSemi NCP5322A controller chip as the heart of the A7V333, providing a state of the art solution for fast and

smooth power regulation.
