Design Envelope
The HIP6301EVAL2 was designed to meet the performance
envelope outlined in Table 1. As such, the design covers the
full range of foreseeable upcoming Pentium 4 processors.
TABLE 1. HIP6301EVAL2 OUTPUT PARAMETERS
Figure 2 details the converter’s response to a low-frequency
55A transient. As it is evident from the scope capture, the
design implements output voltage droop as a means to meet
the dynamic transient requirements while employing a
minimum amount of output capacitance. The nominal no-
load output voltage is also offset low by design. Strict power

HIP6301EVAL2 Performance
Output Soft-Start
The HIP6301 controller undergoes a soft-start cycle each
time power-on reset (POR) transitions from high to low (input
bias application), or when the chip is enabled for operation

(FS/DIS pin released from a pull-down). Figure 1 details an

time T0, then the circuit is disabled by shorting the FS/DIS
pin to ground. At time T0, the FS/DIS pin is released from
the short-circuit to ground, and shortly thereafter, the output
voltage starts to ramp up. The low-frequency ripple visible in
the current drawn from the input supply is a result of the
digital soft-start building the output voltage in small

increments. Similarly, this stepping method is reflected into
the output voltage and the COMP pin waveforms.

is performed to detail the swift response of the converter and
the tight output voltage regulation across a typical range of
output loading. The short-duration spikes exceeding the 1.70V
maximum level would be further reduced in a practical
implementation: the processor current transient has a softer
turn on/off characteristic than the EMT test tool.

At time T1, the output voltage is sufficiently high to allow the
electronic load to draw the full 10A. At time T2 the soft-start
cycle ends and the PGOOD pin is enabled to report the
result of the output monitoring function.
