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 cycle.
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
. See Figure 23.
2. Offset Tracking
The intended start-up sequence is shown in Figure 24. In
this configuration, V
C
will not start until V
P
reaches a preset
value of:
