TRANSIENT RESPONSE
The standard ADDC02808PB is designed to deliver large
changes, or pulses, in load current with minimum output volt-
age deviation and an ultrafast return to the nominal output
voltage. The compensation of the feedback loop is optimized,
and output stability is insured, for a broad range of external load
capacitance extending from 500
µF (R
ESR = 20 m
Ω) to 4,000 µF
(RESR = 2.5 m
Ω). The variables that impact pulse performance
(the maximum output voltage deviation and the settling time)
are:
1. Size of step change in the output current.
2. Amount of external load capacitance.
3. Internal compensation of the feedback loop (factory set).
4. Connection from converter output to load.
Extensive modeling of the converter with ADI proprietary soft-
ware permits analysis and prediction of the impact each of these
parameters has on the pulse response. The analyses in this data
sheet are based on the load capacitance being comprised of
100
µF, 100 mΩ tantalum load capacitors such as the CSR21
style. Figure 18 is the prediction of the standard converter’s
response to a 24 A step change in load current (from 1 A to
25 A) with a load capacitance of 1,000
µF (R
ESR = 10 m
Ω).
This is very close to the measured pulse response under the
same conditions shown in Figure 6.

Step Change
If the step change is less than 24 A, the pulse response will
improve. For instance, with a 12 A step change, Figure 19
shows a comparison of the response for a 24 A step change and
a 12 A step change in load.
Load Capacitance
Varying the external load capacitance and associated RESR be-
tween the range of CLOAD = 500
µF (R
ESR = 20 m
Ω) and C
LOAD
= 4,000
µF (R
ESR = 2.5 m
Ω) results in the predicted waveforms
shown in Figures 20, 21, and 22. As can be seen, the larger the
capacitor, the smaller the deviation, but the longer the settling
time. Table I lists the maximum output voltage deviations and
settling times for the four combinations of CLOAD and RESR
mentioned above. Note that these are based on the standard
compensation for the feedback loop.
