Loop gain
measurement of DC-DC
converter |
|
|
|
|
By measuring the loop gain characteristic of the
DC - DC converter under the actual voltage applied to, We
quantitatively evaluate circuit stability from phase margin
and gain margin.

Conditions |
|
|
Load: DC-DC converter with switching frequency
1MHz
Sweep frequency 100Hz to 1MHz, Insertion resistor 51 ohm

Results |
|
|
•
|
Phase margin, gain margin.
|
|
|
|
The larger the margin, the more ringing and
oscillation can be suppressed.
|
|
|
•
|
Crossover frequency
|
|
|
|
It is a guide of responsiveness at load
fluctuation. |
|
|
|
|
With marker search function, phase margin and gain margin can
be detected automatically. |
