APPLICATIONCONSIDERATIONS
Limited Output Voltage Resolution: The internal voltage
control feedback loop has limited resolution. Therefore, the output
voltage will exhibit discrete steps as the loop responds to changes
in line, load, trim, or remote sense. For instance, on close
examination,thestartupramphasa“stair-step”shape.Likewise,
a load transient response will be composed of multiple discrete
steps. The size of each step is well determined, and is shown in
FigureC.Aclose-uppictureofasinglestepisshowninFigureD.
Stepping will not occur under steady state conditions.
Current share and active trim not recommended: It is
important to note that external feedback control using the sense
or trim pins will cause sustained stepping. External current
share or active trim circuits contain a separate reference voltage.
After this external feedback has taken control, the actual output
voltage can still differ from the external reference voltage by as
muchasthestepsize.Iftheexternalfeedbackloopintegrates
thiserrorvoltage,itwillcausealimitcycleoscillation.Forthis
reason, external feedback using the sense and trim pins is not
recommended.
Input System Instability:Thiscondition can occur because
any DC/DC converter appears incrementally as a negative
resistance load. A detailed application note titled “Input System
Instability” is available on the SynQor website which provides
an understanding of why this instability arises, and shows the
preferred solution for correcting it.
