Power Tracking
The power tracking pins STP and STN are the inputs to a
comparator, whose HI output forces the PWM controller to
skip switching cycles.
1. Linear Tracking
In this application, it is always the case that the lower voltage
supply V
C
tracks the higher output supply V
P
. Please see
Figure 22 below.
