Application Note 9672
± 80mV with the droop function compared to a deviation of
over ± 130mV 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 HIP6004EVAL1 implements the droop function by using
the average voltage drop across the output inductor. The
average voltage drop equals the DC output current times the
DC winding resistance of the output inductor. Instead of
straight voltage feedback, an averaging filter (R8, R9, and
C25 in the schematic) is added around the output inductor.
This filter communicates both the output voltage and droop
information back to the PWM controller. A resistor (R2)
increases the light-load voltage above the DAC program level.
OC Protection
The HIP6004EVAL1 has lossless overcurrent (OC)
protection. This is accomplished via the HIP6004 current-
sense function. The HIP6004 senses converter load current
by monitoring the drop across the upper MOSFETs (Q1-2).
By selecting the appropriate value of the OCSET resistor
(R7), an overcurrent protection scheme is employed without
the cost and power loss associated with an external current-
sense resistor. The HIP6004 Data Sheet details the design
procedure for the OCSET resistor.
OV Protection
The HIP6004EVAL1 contains circuitry to protect against
overvoltage conditions. In the case of an overvoltage
(greater than 15% over the nominal Vout), the HIP6004 fires
an SCR (Q8) and the input fuse will open.
For applications where this feature is not necessary, the
following components may be eliminated: F1, Q8, and R6. A
wire must replace F1 when using HIP6004EVAL1 without
OV protection.

Conclusion
The HIP6004EVAL1 is a reference design suitable for a
DC-DC converter solution for the Pentium-Pro and other
high-performance microprocessors.
