power supply products designed for card-level applications. These are sophisticated 1 of N
configurable miniature systems to simplify driving power-hungry dense components such as
FPGAs and processors. The extremely high instantaneous switching currents needed to
support high speed chips are provided by Point-of-Load regulators. The POL regulators can
be monitored and controlled by the Shelf Manager. For example, the SM can adjust the
conversion clock frequency and phase for noise minimization. Figure 3 is a block diagram of
a typical suite of power components.IP PBX Example
