Application Note 9706
converter still meets ± 5% regulation with a 2.8V output, but
with less margin than with all nine output capacitors. At
lower output voltages, such as 2.0V, the converter would
not meet the regulation requirement.
Figure 12 shows the HIP6005EVAL3 transient response to a
0.2A-14A transient with only five output capacitors. Its
response also meets the regulation requirements but with
little margin. It is very likely that, with manufacturer

variations, the converter will exceed the regulation window in
response to this large of a load transient.

Changing the output filter of the converter affects the control
loop characteristics in general. Reducing the number of
output capacitors from nine to five pushes the L-C break
frequency of the output filter out slightly and increases the
0dB crossover frequency. It also reduces the amount phase
margin slightly, but there is still adequate phase margin with
five output capacitors.

Reducing the number of output capacitors is possible but
should be examined from a system standpoint. If the
converter regulation requirement is firm at ± 5%, and the
microprocessor core voltage can approach 2V, and the
transient requirements approach 12A-14A steps, than the
unmodified reference design (with nine output capacitors)
should be employed. If one or more of these requirements is
relaxed, than the number of capacitors may be reduced with
satisfactory results.
Transient Testing with Intel Test Tool
When testing the transient response of the HIP6004/5EVAL3
with an Intel-supplied test tool, some care must be taken for
proper results. Jumpers JP0-4 must be installed on the
evaluation board for proper operation of the converter. This
is because the test tool uses CMOS output drivers on the
VID signals, which are incompatible with the analog nature
of VID0-4 on the HIP6004 and HIP6005. This is only an
issue with the test tool and not any known microprocessor
architecture. Grounding the five VID signals programs the
converter output voltage to 2.05V and allows transient
testing at this voltage. As shown in this application note,
transient testing at this voltage level provides validation of
the reference designs.
There is an additional jumper on the evaluation boards. JP5
is normally installed and must be removed if the Intel test
tool is installed and the converter input source exceeds 5.5V.
The Intel test tool uses Vcc5 for its bias source and JP5
connects IN of the evaluation board to Vcc5. If the evaluation
board IN voltage is 5V, than JP5 can remain installed. If IN is
12V, than JP5 must be removed and an external 5V must be
applied to Vcc5. See the schematics in the appendix for
more details.
