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 VTM output 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 below 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_O.

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.
