Transient Load At 2.1V Out
Performance at 2.1 volts out is very similar
to that at 3.5 volts. The notable exception
is a reduction of the negative spike at the
current rising edge. This is due to having
more average voltage available to change
the current in L1.

Input di/dt During Transient Load
The Intel guideline (optional) specification
calls for a maximum input di/dt during
transient load of 0.1A/μs. The IRP6VRM1
readily meets this specification at turn on,
but falls short at turn off.
This is common to all VRM boards evaluated
by IR, regardless of manufacturer. It should
not cause difficulties for most users, but if it
is an issue for your design, add input
inductance.
