PRELIMINARY
Overview of Adaptive Loop Compensation
Adaptive Loop compensation, illustrated in Figure 1, contributes to
the bandwidth and speed advantage of Factorized Power. The PRM
monitors its output current and automatically adjusts its output
voltage to compensate for the voltage drop in the output
resistance of the VTM. R
OS
sets the desired value of load voltage,
Vout; R
CD
is set to a value that compensates for the output
resistance of the VTM (which, ideally, is located at the point of
load). For selection of R
OS
and R
CD
, refer to Table 1 or Page 9.
The VI Chip’s bi-directional VC port :
1. Provides a wake up signal from the PRM to the VTM that
synchronizes the rise of the VTM output voltage to that of the PRM.
2. Provides feedback from the VTM to the PRM to enable the PRM
to compensate for the voltage drop in VTM output resistance, R

— Configure your Chip Set using the PRM-AL
Figure 1
— With Adaptive Loop control the output of the VTM is regulated over the load current range with only a single interconnect between the PRM and
VTM and without the need for isolation in the feedback path.
