ADVANCED INFORMATION
APPLICATION INFORMATION (CONT.)
V
IN
= 5 V I

= 100 mA
Full Cycle
Switching to Linear
During the transient response between the “Buck” and “Linear” control modes the output voltage needs to stay within
the regulation requirements.
The following scope pictures show the changes in the output voltage during these transients. As can be seen, the
maximum drop is about 80 mV and maximum overshoot is negligible.
In switching from the “Buck” mode to the “Linear” mode the settling time is less than 250
μ
sec over the supply range
of 5 V to 3.2 V for this 3.0 V application.
