When the output voltage reaches the specified value
(1.80 V or 3.0 V or 5.0 V), Q1 and Q16 are switched
OFF immediately to avoid over voltage on the output
load. In the mean time, the two extra NMOS Q2 and
Q3 are switched ON to fully discharge any current
stored into the inductor, avoiding ringing and
voltage spikes over the system. Figure 16 illustrates
the theoretical basic waveforms present in the
DC/DC converter.
The control block gives the logic states according to the
bits provided by the external P. These controls bits are
applied to the selected DC/DC converter to generate the
programmed output voltage. The MOS drive block includes
the biases necessaries to drive the NMOS and PMOS
devices as depicted in the block diagram given Figure 15.
