FIGURE 7. 0A TO 14A TRANSIENT RESPONSE
The HIP6004EVAL1 uses a droop function to maintain
output voltage regulation through load transients with fewer
(or less costly) output capacitors. With a high di/dt load
transient typical of the Pentium-Pro microprocessor, the
largest deviation of the output voltage is at the leading edge
of the transient. The droop function adds a deviation as a
function of load that counters the transient deviation.
Figure 9 illustrates the static-load droop characteristic. With
no-load, the output voltage is above the nominal output
level. The output decreases (or droops) as the load
increases.
Output Voltage Ripple

WITHOUT DROOP
The HIP6004EVAL1 has ten parallel output capacitors,
mainly to supply the energy during the severe load
transients imposed by high-performance microprocessors.
This also helps provide a very low output voltage ripple, as
shown in Figure 8. With approximately 2A peak-to-peak (p-
p) inductor ripple current, the output voltage ripple is only

about 12mV P-P . Including noise spikes, the total output
deviation with this 12ADC load is about 20mV P-P
(measurement is taken with a 20MHz oscilloscope

bandwidth).
If the application does not have a highly dynamic load, then
the number of output capacitors may be reduced. The output
voltage ripple increases with fewer output capacitors. For
instance, with just five output capacitors in parallel, the
output voltage ripple doubles to approximately 24mV P-P .
FIGURE 9. STATIC REGULATION OF THE HIP6004EVAL1
With a dynamic load, the droop function pre-biases the
output voltage to minimize the total deviation. Prior to the
application of load, the output voltage is above the nominal
level and the transient deviation results in an output lower
than the nominal level. Figure 6 illustrates the droop function
performance on the HIP6004EVAL1 converter. The transient
deviation is approximately 130mV. At light load, the output
voltage is about 50mV higher than the nominal output
voltage of 2.8V. At full load, the output voltage is about
40mV lower than nominal. The total deviation is within
