|
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. |
