FIGURE 5. HIP6005EVAL3 EFFICIENCY vs LOAD
Transient Response
Figures 6 and 7 show laboratory oscillograms of the
HIP6005EVAL3 which are similar to those shown in Figures
3 and 4 for the HIP6004EVAL3. There are small differences
in the transient responses of the two different evaluation
boards. Since the HIP6005EVAL3 uses a larger output
inductor and identical control loop compensation (R5, R8,
C8, and C9), the closed-loop gain crossover frequency is
lower than for the HIP6004EVAL3. Check the Feedback
Compensation section of either data sheet for details on loop
compensation design. Table 1 details simulated closed-loop
bandwidth and phase margin for both reference boards at
both +5V and +12V input sources.

Output Voltage Droop with Load
Both the HIP6004EVAL3 and HIP6005EVAL3 use 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
voltage change as a function of load that counters the transient
deviation.
Figure 8 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.
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 3 illustrates the droop function
performance on the HIP6004EVAL3 converter. The transient
deviation is approximately 110mV. At light load, the output
voltage is about 50mV higher than the nominal output
voltage of 2.05V. At full load, the output voltage is about
60mV lower than nominal. The total deviation is within

± 60mV with the droop function compared to a deviation of
over ± 100mV without this function. Since the voltage
excursions at the transient edges are mainly a function of the
output capacitors, the converter uses fewer capacitors.

The HIP6004/5EVAL3 implements the droop function by
using the average voltage drop across the output inductor.
